[CMake] Add mac-performance preset with PGO/LTO support
https://bugs.webkit.org/show_bug.cgi?id=319174
rdar://182009951
Reviewed by Elliott Williams.
Add a new preset: mac-performance that enables PGO/LTO. The goal of this
mode is to reflect any future shipping CMake build as much as possible.
I didn't enable PGO by default for release builds with the internal SDK
because it does seem to noticeably slow down the build (1:50-2:00
without PGO vs 2:10-2:20 with for `--target jsc` builds).
When PGO is enabled for internal SDK builds it uses an OptionsPGO.cmake
to configure PGO data and disables the OSS PGO CMake logic.
