[roll third_party/pigweed] pw_protobuf: Distinguish between string and bytes fields
Use a MessageField bit to indicate that the field is a string field, as
opposed to a bytes field. Dedicating a bit to one specific type is an
inefficient use of the field_info_ bits, but there were bits to spare
and this was the simplest way to do this. If more field_info_ bits are
needed in the future, a few of the existing fields could be consolidated
into a single 4-bit field_type that specifies that precise type (e.g.
int32, fixed64, message, etc.).
It is necessary to distinguish between string and bytes in order to
switch from using pw::Vector<char> to pw::InlineString<> for string
fields.
This change also updates C++ codegen to include /*attr_name=*/ comments
for bool arguments to improve readability.
