[roll third_party/pigweed] pw_protobuf: Don't write empty fixed sized fields

Fixed sized fields are an implementation detail of pw_protobuf, and
should behave identically on-wire to those implemented with pw::Vector.
This means not encoding when they have a zero (default) value, for
compatibility with other protobuf implementations.

Confirmation that this is correct behavior is that after this, tests
for certain fields no longer need to include expected zero values
of random other fields.
