[Remarks] Add support for linking remarks

Remarks are usually emitted per-TU, and for generating a standalone
remark file that can be shipped with the linked binary we need some kind
of tool to merge everything together.

The remarks::RemarkLinker class takes care of this and:

* Deduplicates remarks
* Filters remarks with no debug location
* Merges string tables from all the entries

As an output, it provides an iterator range that can be used to
serialize the remarks to a file.

Reland: [Remarks] Add an LLVM-bitstream-based remark serializer

Add a new serializer, using a binary format based on the LLVM bitstream
format.

This format provides a way to serialize the remarks in two modes:

1) Separate mode: the metadata is separate from the remark entries.
2) Standalone mode: the metadata and the remark entries are in the same
file.

The format contains:

* a meta block: container version, container type, string table,
external file path, remark version
* a remark block: type, remark name, pass name, function name, debug
file, debug line, debug column, hotness, arguments (key, value, debug
file, debug line, debug column)

A string table is required for this format, which will be dumped in the
meta block to be consumed before parsing the remark blocks.

On clang itself, we noticed a size reduction of 13.4x compared to YAML,
and a compile-time reduction of between 1.7% and 3.5% on CTMark.
