Description

Fix regression incorrectly advertising TH support

--supported-languages must only advertise language extensions
which are supported by the compiler in order for tooling such
as Cabal relying on this signalling not to behave incorrectly.

Fixes Trac #16331

(cherry picked from commit db4372cda7f6c87e7ad26efe3fca4b3f7f527a48)
