Reapply [pseudo] Move pseudoparser from clang to clang-tools-extra" This reverts commit 049f4e4eab19c6e468e029232e94ca71245b0f56. The problem was a stray dependency in CLANG_TEST_DEPS which caused cmake to fail if clang-pseudo wasn't built. This is now removed. GitOrigin-RevId: 89cd86bbc58afe7d036bdb2f656dca38b62d8ef0
