BaseTools/tools_def AARCH64: enable frame pointers for RELEASE builds

Commit 8f0b62a5dac0 ("BaseTools/tools_def AARCH64: enable frame pointers
for DEBUG builds") removed the -fomit-frame-pointer switch from the CFLAGS
definitions that are shared between AARCH64 DEBUG and RELEASE builds, and
moved it to the RELEASE specific ones, so that DEBUG builds can produce a
backtrace when a crash occurs.

This is actually a useful thing to have for RELEASE builds as well. AArch64
has 30 general purpose registers, and so the performance hit of having a
frame pointer is unlikely to be noticeable, nor are the additional 8 bytes
of stack space likely to present a problem.

So remove -fomit-frame-pointer altogether this time.
