[roll third_party/pigweed] pw_protobuf: Add inline option support

Adds inline field option support for max_size and max_count fields, as
recently discussed in PW Live. This makes a distinction between
protocol-level parameters vs codegen configuration, where specifying
these fields inline should only be used in cases where they affect
protocol validity.
