(cherry picked from commit 35a15e619161798820b2bd6ff46178c5b7ccebcf)
Adds support for LTO on macOS and Android.
Disable LTO by default on iOS even if `production=yes` is set.
Also add `linker` option to `server` platform missed in #63283.
Refactor code handling old arguments to make it simpler (breaks compat,
but is explicit enough about it and scripts are easy to fix).
Previously it was used only on debug builds, but recent
additions to variant_call.cpp have made that unit too
large even in release_debug.
It was originally set to debug only because using it
breaks mingw, so this only reinstates it for MSVC where
it shouldn't have any drawbacks (famous last words).
Test-Information:
Builds for me with
scons -j 40 platform=windows target=release_debug
and my game then runs from it.
