GHA: enable H3 proxy in CI, also enable h2o tests on Linux
Also:
- GHA/http3-linux: enable deprecated APIs in openssl-prev local
  OpenSSL builds. Required by h2o and its vendored dependencies.
  Tried OpenSSL 4, LibreSSL 4.x, BoringSSL: all failed at one point.
- GHA/http3-linux: build h2o from source.
  libuv1-dev may not be stricly required.
  Tried installing libwslay-dev, but it wasn't recognized.
  Also disable building h2o libs for a much smaller dist directory and
  slightly faster build.
  Sadly, h2o is not versioned, so I pinned to the current latest commit
  at the master branch. It advertises itself as 2.3.0-DEV in pytest.
- drop redundant `libnghttp3` installs. Remains of openssl-quic builds.
  Follow-up to 6aaac9dd38 #20226

Note GHA/macos pytests may or not not be stable with the H3 proxy tests.

Follow-up to e78b1b3ecc #21153

Closes #21789
