Glasgow Haskell Compiler | Fix #16133 by checking for TypeApplications in rnExpr (!77)

For what it's worth, the !77 seems to mean
https://gitlab.haskell.org/ghc/ghc/merge_requests/77 which is also the
"View it on GitLab" link target. And in general the "!" seems to indicate a
merge request, per reference to "!82" mentioning this one. So this does
seem to be a new merge request, and presumably the third part is the
requested merge from a personal WIP branch to master.
