fix(measured-boot): don't strip last non-0 char
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.
