  [flang] Correctly handle -mframe-pointer=reserved (#146937)

Fixes `#146802`

#146582 started using the `Reserved` Frame Pointer kind for Arm64
Windows, but this revealed a bug in Flang where it copied the
`-mframe-pointer=reserved` flag from Clang, but didn't correctly handle
it in its own command line parser and subsequent compilation pipeline.

This change adds support for `-mframe-pointer=reserved` and adds a test
to make sure that functions are correctly marked when the flag is set.
