Fix AMD64 epilog ABI (#54357)

* Fix AMD64 epilog ABI

The Windows AMD64 epilog ABI states that an `lea rsp,[rbp+constant]` instruction
may only be used if a frame pointer has been reported to the OS in the prolog
unwind info, otherwise an `add rsp, constant` instruction must be used.
There were a number of cases where the JIT used the `lea` form simply because
a frame pointer had been established and was available, even though it had not
been reported to the OS (and, thus, the frame was effectively an `rsp` frame).

Fix this by using the same condition in the epilog for determining which form
to use, `lea` or `add`, that was used in the prolog to determine whether or not
to report the frame pointer in the unwind info.
