util/ifittool: Error out if microcodes do not fit the FIT table

parse_microcode_blob() returns success when it reaches max_fit_entries
microcode. It makes the FIT table size verification in
fit_add_microcode_file() useless. This patch makes
parse_microcode_blob() error out if max_fit_entries is reached.

Note that this size verification is critical as a FIT table only
partially listing the microcode patches can lead to boot failures as
recently observed on Raptor Lake-P.

BRANCH=firmware-brya-14505.B
BUG=b:245380705
TEST=compilation errors out when trying to stitch more than
     CONFIG_CPU_INTEL_NUM_FIT_ENTRIES microcode patches.
