pw_varint: use std::byte instead of uint8_t

This change switches pw_varint to using spans of std::byte instead of
uint8_t for encoding and decoding. The pw_protobuf module, which uses
pw_varint, is also updated.

A ToString formatter for std::byte is also added to pw_string (required
to use std::byte in unit test EXPECT statements).
