check_config.h was included manually by custom configuration files.
This caused compilation errors when updating MbedTLS to 3.6.0
because check_config.h was processed too early, before the whole
configuration is defined, effectively causing configuration check errors.
MbedTLS already takes care of including check_config.h at the right time.
Remove those erroneous manual check_config.h includes.

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 patch refactor the RSA operations done by the signature verification
module and by the encrypted images decryption module. Previous solution is
tightly coupled with Mbed TLS, while this patch provides an abstraction of
the RSA functionalities in a dedicated crypto abstraction header, crypto/rsa.h
that supports both Mbed TLS APIs and PSA Crypto APIs. In case of PSA Crypto,
the verification scheme is directly provided by the crypto backend hence it
simplifies the operations done in the image verification module.

When building mcuboot-sys, the build script currently adds some
duplicate files. When used as a library, this works, because the code
is linked in as a library. However, when mcuboot-sys is tested itself,
all specified files will be brought in, which results in duplicate
symbols for these files.
Fix this by keeping track of all of the files that we've added, and
making sure to add each file once. Additionally, instead of using the
orphaned files in mbedtls-asn1, just always use the verions in the main
mbedtls library. There are some configurations of the code that end up
using both the extracted files and the full mbed TLS. Avoid that
conflict by just always using the full tree.

When collected together as a workspace, the test framework ends up
running all of the configurations on each project. One configuration
option `large-write` doesn't really mean anything to mcuboot-sys, but
adding support for the feature allows this package to be tested along

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.

Allow the sim to test configurations with MCUBOOT_RAM_LOAD defined.
This does not define any tests for this mode.
This adds definitions for simulated RAM offsets to the simulator. This
will define the offset (from `IMAGE_RAM_BASE`) to where the simulated
RAM will be located. For now, just give these somewhat reasonable
values so that we are able to at least compile the RAM_LOADING code in
the simulator.

Add Mbed TLS ECDSA signature verification as an option (in addition to
Tinycrypt and the CC310 hardware version). Although the Mbed TLS ECDSA
verification code is both larger and slower, this will still save space
if there is another reason that the Mbed TLS code is already being
brought in for another reason (such as certificate management, for
example).
Mbed TLS's ECDSA verification works at a different level than the other
two libraries, so this takes a bit of reworking. There are some
additional parameters passed to the various functions, and a new define
MCUBOOT_ECDSA_NEED_ASN1_SIG to indicate that the ecdsa verification
wants the original ASN1 signature, not a decoded key.
This adds the boot changes and simulator support to test this configuration.

Removes the current `flash_area_read_is_empty` which lacked a bit of
clarity in its naming and error handling, as well as requiring an
extra API in the flash map, and switches to using an internal function
`bootutil_buffer_is_erased`.
Code that was previously using `flash_area_read_is_empty` must now be
updated to do a `flash_area_read` followed by a call to
`bootutil_buffer_is_erased` with the read buffer.
