Add missing compilation guards for GCM and CCM

Add missing compilation guards that broke the build if either GCM or
CCM was not defined.
Add missing guards on test cases that require GCM or CBC.
The build and tests now pass for any subset of {MBEDTLS_CCM_C,
MBEDTLS_GCM_C}. There are still unused variables warnings if neither
is defined.

mbedtls_ctr_drbg_update_ret: correct doc for input length limit

Unlike mbedtls_ctr_drbg_update, this function returns an error if the

Create the NV seed file for the tests if needed
...
Write an all-bits-zero NV seed file for the tests. Without this, if
the seed file is not present when this test suite is executed, the
PSA module initialization will fail, causing most test cases to fail.
Also write an all-bits-zero NV seed file at the end. The test cases in
this test suite mess with the file, but subsequent test suites may
need it.

Support NV seed enabled at compile time but not at runtime

When testing with custom entropy sources, if MBEDTLS_ENTROPY_NV_SEED
is enabled at compile time but the NV seed source is not used at
runtime, mbedtls_entropy_func makes a second pass anyway. Cope with
this in the test code by telling the entropy module not to make this
second pass.

When MD or CMAC are disabled, let the compiler know that it is OK that
`key_bits` is set but not used by casting `key_bits` to `(void)`.

check-files: Don't check same-named files
...
The check-files script contains the strings "TODO" and "todo" in order to
search for files that contain TODO items. So, any check-files script would
need to be excluded from the list of files that gets checked for "TODO".
Normally, the script excludes itself from checks, but with the addition of
the crypto submodule, there is another copy of the script present from the
project root. We must avoid checking check-files scripts for TODO items.
This also helps if you run check-files from another working tree in your
working tree.

pk_wrap: rework signature extraction to work with small r and s values

There is a probability that r will be encoded as 31 or less bytes in DER,
so additional padding is added in such case.

Add tests for ECDSA verify with short r, s values

This is intended to test transcoding the signature to the format expected by
PSA (fixed-length encoding of r, s) when r and s have respectively:
- full length with initial null byte
- full length without initial null byte
- non-full length with initial null byte
- non-full length without initial null byte
