The max size macros of metadata elements are shared across
multiple measured boot backends: rss-measured-boot, dpe.
Increase the SW_TYPE_MAX_SIZE to be able to accomodate
all macro.

With the current implementation of stripping the last null
byte from a string, there was no way to get the TF-M measured
boot test suite to pass. It would expect the size of the string
passed into extend measurement to be unaffected by the call.
This fix should allow passing a string with the null char
pre-stripped, allowing the tests to exclude the null char in
their test data and not have the length decremented.
Further, This patch adds an early exit if either the version
or sw_type is larger than its buffer. Without this check,
it may be possible to pass a length one more than the maximum,
and if the last element is a null, the length will be truncated
to fit. This is instead suppsed to return an error.

Remove the null-terminator of the string-like data items
from the RSS measurement's metadata. The 'version' and
'sw_type' items have an associated length value which
should not include a null-terminator when storing the
measurement.

This API is added for testing purposes. It makes possible to write test
cases that read measurements back after extending them, and compare
them to expected results.

A secure enclave could provide an alternate
backend for measured boot. This API can be used
to store measurements in a secure enclave, which
provides the measured boot runtime service.
