Add utilities for reading and writing of counter data files as part of
the new code coverage implementation.
Trivia note: currently the contents of counter data files are emitted
in little-endian form, which for the counters is somewhat painful in
that we need to visit each counter value and properly encode it. It
might be better to instead emit counters in native endianity and then
teach the tools to decode properly in the case of an endianity
mismatch.
Updates #51430.

Add a coverage meta-data decoder, which provides APIs for reading
encoded coverage meta-data and expanding it usable form. This package
is intended to be used in the coverage tooling that reads data files
emitted from coverage runs. Along with the new decoding package is a
unit test that runs the encode/decode paths together to check to make
sure that "decode(encode(X)) == X".

Add a new package with APIs for encoding coverage meta-data. This
provides support for accumulating information about each function
during the compilation process, and then encoding and emitting a
payload for a coverage meta-data symbol. Not yet connected to the
rest of the coverage machinery (that will appear in a later patch).
