Aiden Grossman 4c80193a58 Revert "[clang] Remove %T from tests (#151614)"
This reverts commit 5a586375aa3a128dadc9473cfa196bf8588c2a82.

This breaks two buildbots with failures in
implicit-module-header-maps.cpp. No idea why these failures are
occurring.

// 2) header maps aren't used, as the header name doesn't exist and relies on
// the header map to remap it to the real header.
