Merge branch 'development-psa-proposed' into development

Resolve conflicts by performing the following.

- Take the upstream Mbed TLS ChangeLog verbatim.
- Reject changes to Makefiles and CMake that are related to using Mbed
  Crypto as a submodule. It doesn't make sense to use Mbed Crypto as a
  submodule of itself.
- Reject README changes, as Mbed Crypto has its own, different README.
- Reject PSA-related changes to config.h. We don't want to disable the
  availability of the PSA Crypto API by default in the Mbed Crypto
  config.h.
- Don't inadvertently revert dead code removal in
  mbedtls_cipher_write_tag() which was added in f2a7529403 ("Fix
  double return statement in cipher.c")
- Where Mbed Crypto already had some MBEDTLS_USE_PSA_CRYPTO code (from
  past companion PRs) take the latest version from Mbed TLS which
  includes integration with MBEDTLS_CHECK_PARAMS.
- Update the version of the shared library files to match what's
  currently present in Mbed TLS.
- Reject removal of testing with PSA from config full tests.
- Resolve conflicts in test tests/suites/helpers.function, where both
  Mbed Crypto and Mbed TLS both added documentation for TEST_ASSERT.
  Combine text from both documentation efforts.
- Reject adding a submodule of ourselves.
- Reject addition of submodule tests in all.sh.
- Reject addition of submodule to library path in
  tests/scripts/run-test-suites.pl.
- Avoid using USE_CRYPTO_SUBMODULE=1 in
  component_test_use_psa_crypto_full_cmake_asan() in all.sh.

/**
* \def MBEDTLS_CHECK_PARAMS
*
* This configuration option controls whether the library validates more of
* the parameters passed to it.
*
* When this flag is not defined, the library only attempts to validate an
* input parameter if: (1) they may come from the outside world (such as the
* network, the filesystem, etc.) or (2) not validating them could result in
* internal memory errors such as overflowing a buffer controlled by the
* library. On the other hand, it doesn't attempt to validate parameters whose
* values are fully controlled by the application (such as pointers).
*
* When this flag is defined, the library additionally attempts to validate
* parameters that are fully controlled by the application, and should always
* be valid if the application code is fully correct and trusted.
*
* For example, when a function accepts as input a pointer to a buffer that may
* contain untrusted data, and its documentation mentions that this pointer
* must not be NULL:
* - the pointer is checked to be non-NULL only if this option is enabled
* - the content of the buffer is always validated
*
* When this flag is defined, if a library function receives a parameter that
* is invalid, it will:
* - invoke the macro MBEDTLS_PARAM_FAILED() which by default expands to a
* call to the function mbedtls_param_failed()
* - immediately return (with a specific error code unless the function
* returns void and can't communicate an error).
*
* When defining this flag, you also need to:
* - either provide a definition of the function mbedtls_param_failed() in
