If the compile-time configuration enables an option that was removed
in Mbed TLS 3.0, and the effect of removing the option would likely
not be detected at build time, #error out in check_config.h.

Note on naming: previously considered input_numeric but then thought the
other two input function are "input <name>" not "input <adjective>" so
decided to follow that pattern. input_int would be shorter but sounds
too much like the C type, which could be confusing as that's not the
type of the parameter; IMO "integer" avoids that problem.

For the numeric values, I followed the apparent existing convention:
- first byte is 01 for secret inputs, 02 for non-secret inputs
- then second by is just incremented for each new input type
The documentation references a function that will be introduced in the
next commit.

The documentation references functions that will be introduced in later
commits, but hopefully from the naming it's already clear what those
function will do.

Question to reviewers: regarding the numeric values, I'm not sure I've
incremented the right byte/nibble. Should this be 0x1201, 0x1202
instead, or something else? Is there a convention I should be aware of?

Specifically allow the driver to override the persistency level of a
builtin key in cases where the driver is persistency-aware.

The GCM interface now has separate functions to start the operation
and to pass the associated data.
This is in preparation for allowing the associated data to be passed
in chunks with repeatated calls to mbedtls_gcm_update_ad().

Alternative implementations of GCM may delay the output of partial
blocks from mbedtls_gcm_update(). Add an output length parameter to
mbedtls_gcm_update() to allow such implementations to delay the output
of partial blocks. With the software implementation, there is no such
delay.

Alternative implementations of GCM may delay the output of partial
blocks from mbedtls_gcm_update(). Add an output parameter to
mbedtls_gcm_finish() to allow such implementations to pass the final
partial block back to the caller. With the software implementation,
this final output is always empty.

Due to repeated calls to PSA_AEAD_NONCE_LENGTH, which in turn calls
PSA_ALG_AEAD_WITH_DEFAULT_LENGTH_TAG several times, some macros updated
in this PR expanded to over 6000 characters, more than the 4095 that ISO
C99 compilers are guaranteed to support.

Where a change was necessary, the new documentation was copied from the
PSA Crypto API spec exactly, with the exception of PSA_AEAD_TAG_LENGTH,
which needed some adjustment.
