If the psa-crypto-api feature is defined, the simulator will
initialize the PSA Crypto API exactly once. It needs also to
enable the test external RNG as the assumption is that the
PSA subsystem is configured to use MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG

This commit adds simulator support to test the
hw-rollback-protection feature which is using
nv-counters. In the simulator they are stored in Rust
to prevent any race conditions from happening due to
the parallel execution of the tests.

Combine all of the pieces to be able to test ram loading with multiple
images. We construct a model `RamData` that indicates where each image
should be loaded into RAM. This has to be made early enough to compute
signatures on the images, and then used later to verify that the images
were loaded properly.

Test the basic configuration for ram loading. Instead of a fixed
address for RAM, the values come dynamically from a thread-local
variable (allowing the tests to run in parallel). The size of the ram
along with the address of the buffer in the test address space are
passed in this way.
This tests the single-image configurations of ram loading. Testing
multi-image will take additional work, as the RAM will need to be large
enough for both images, and the second image will need a meaningful
offset address in RAM.

Add new bootutil function that returns the size of the status area.

* Adds a new level (BOOT_LOG_SIM) to be used only for messages that
are interesting while debugging bootutil in the simulator. This should
be used for extra verbose prints.
* Also added fflushs after fprints to guarantee that messages are printed
even when assertions are raised.
* For abstraction completeness, add "do nothing" definitions of _LOG_SIM
to the other ports.
* Make DEBUG the default level when building the simulator (one can
still lower verbosity using any other value for RUST_LOG).

Convert this `extern const uint32_t` to a simple define. Provide an
accessor function so that the simulator is able to access the value as
well. This has a minor improvement on the generated code within MCUboot
itself.

BOOT_MAX_ALIGN is defined as
extern const uint32_t BOOT_MAX_ALIGN;
and is assigned a value in a single file. This causes extra work when
this is used as the size of a local variable in a function.
The value was made a constant in order for the simulator to be able to
access the value. Instead of making it a "real" constant, keep it as a
define, unifying the value of FLASH_MAX_ALIGN and this one, and provide
an accessor function for the test code to be able to access this value.
This causes a minor improvement in the code generated in
`boot_write_status`, but more importantly, eliminates a VLA from the
code, which increases the possible compilers supported by MCUboot.

Add a `debug_dump()` method to `Images` to allow the images to be
written to a file. The dependency test will call this if the
environment variable MCUBOOT_DEBUG_DUMP is set.
In order to make these debug dumps more useful, add a simple partition
table to the beginning of the image (where MCUboot would reside on
target). This has a simple header, and then entries for each partition,
using the partition ids used within the simulator. This allows the
image to be more easily used by external tools.
As an example, `scripts/mcubin.bt` is a binary template for the [010
Editor](https://www.sweetscape.com/010editor/), allowing it to decode
and show the details of images from MCUboot.

With the recent changes in bootutil, now there is no need to lock the
test threads to run sequentially, so the global lock was removed. The
locking now happens to access resources such as flash, flash params,
simulator context, etc on a per thread basis. Some of the global
variables that were used by the simulator itself (FFI) were made into a
context struct passed in to invoke_go.

Prior to this change, the scratch image trailer had a different format
from a slot image trailer. Specifically:
1. The scratch trailer only contained a single set of status entries
(three bytes); the slot trailer contained `BOOT_STATUS_MAX_ENTRIES`
sets of status entries.
2. The scratch trailer did not contain the `copy_done` field.
This inconsistency required some extra conditional logic in the trailer
handling code. It is simpler to just use the same trailer format
everywhere.
This commit removes this inconsistency. Now, the scratch trailer
structure is identical to that of the slot trailer.

Construct the ImagesBuilder based on the number of images compiled into
the code. If the flash device doesn't have enough areas for the test,
the test will be skipped.
Extend the FlashId to include Image2, and Image3. Remove the unused
ones, so that these can be placed immediately after the scratcharea.
The current simulator code assumes the flash areas are numbered
contiguously, requiring these extraneous partitions to be eliminated.

The name `SimFlashMap` is a bit misleading, as the Map part is more of
an implementation detail when the type really just represents multiple

This is just a rename, but the names `SimFlashMap` and the value

This change replaces the slot 0/1 terminology with primary/secondary
slot and replaces FLASH_AREA_IMAGE_0/1 with

understandable, fits better to MCUs with multiple images and it is an
architecture agnostic alternative as well.

The previous c/rust ffi functions were hardcoding the values of align
and erased_val before each run through static globals. This adds new sim
flash functions that get the align/erased_val from the sim flash device

each use its own params.

A new align() function was added to SimFlash, and most functions that
were using/receiving align or erased_val parameters that had access to a
Flash trait were cleaned up so that they get the parameters directly
from the Flash device.
This will make it easier to extend for multiple Flash devices since
parameters should depend on the device in use.

When building in simulator mode, mock assert() to call an simulator
function which will enable other code to check if some path failed.
The assert checking interface, was added to boot_go which now
returns the low-level invocation results as well as the number of
asserts triggered.
Some new added tests check for assert() and expect it to happen. To not
abort tests, assert() was changed under sim env to not call c assert()
and instead just do some internal calculation which could be checked
by the simulator after a bootloader run and assert() catching behavior
was made optional (each test choses the behavior it needs).
