@carlossanlop can you get M2 approval from your side?

@jkoritzinsky there was a patch in the main PR in a separate commit: https://github.com/dotnet/runtime/pull/106994/commits

@jkotas do we care to have the commits split in this PR like you requested in my zlib-ng update?

[jkoritzinsky]

@carlossanlop I included those changes into the initial commit in this PR.

This does not have any custom patches that have not been upstreamed, and the changes outside the vendored Brotli are very minimal. I do not have a problem with it all being in one commit.

/ba-g Re-ran failed CI legs and they passed. Only one known/pre-existing failure showed up.
