Currently all the hashing functionality is done with SHA256
but if we would like to use ECDSA-P384 that requires SHA384
as the hashing algorithm. However, MCUboot is using SHA256
for image hashing and public key hashing. This commit modifies
the hashing operations to use SHA384 thus SHA256 can be omitted
which is beneficial from a code size standpoint.

If ram-load is being used with encryption and
the higher version image is loaded from the primary slot the
verification will fail as the image is always non-encrypted
and will produce an invalid hash. This fix puts encrypted images
into both slots to prevent this issue.

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.

The IMAGE_TLV_ECDSA256 TLV has been put out of use by
commit 63d2346da4.
This commit reverts this part of that patch and at the
same time it extends the usage of this TLV to cover all types
of curves (replacing the newly introduced 0x25 TLV type)
while retaining its value (0x22) for backward compatibility.
Rename IMAGE_TLV_ECDSA256 to IMAGE_TLV_ECDSA_SIG.

In order to generate images that match exact sizes, we need to know the
size of the TLV. We can estimate this size before the payload is added
(since the payload doesn't directly affect the size).
This patch adds the size estimate, and compares it with the actual TLV
size.

When building images for testing they are aligned to a flash write size,
which works fine for flash based comparisons, but since RAM is always
reset to 0, if the flash is erased to 0xff, the final bytes of the
alignment will differ even though they are not relevant (not part of the
image itself).
This commit adds a real image size parameter to the ImageData, so it can
be used by the RAM load to compare only the relevant bits of the image
(ignore the padding), and also updates the RAM test routine to use the
correct image size.

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
with all of the other packages.

Instead of having to cd into the 'sim' directory, create a top-level
Cargo.toml file that adds the sim as a workspace.
For the most part, this doesn't change how the simulator works. It is
still possible to run `cargo test ...` within the `sim` directory.
However, the `target` directory will reside at the top-level of the tree
instead of within the sim directory.
One change is that running cargo commands at the top of the tree will
run those commands on all of the packages found within the tree.
Specific packages can be tested by either changing to the directory of
that package, or passing `-p <dir>` to the cargo test command (i.e.
`cargo test -p bootsim`).
The other visible change from this commit is that the 'target' directory
will always be at the top of the tree, rather than in particular
directory where the test is run. Any scripts or tools that expect this
to be in a certainly location, will have to be modified.
