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).
Modules can now call:
env.module_add_dependencies(name: str, deps: list, optional: bool)
To add required or optional dependencies during the "can_build" step.
Required dependencies will be checked and the module will be not be
enabled when they are missing, printing a warning to notify the user.

This is still a bit hacky and eventually we should rework the way we handle
optional dependencies (especially with regard to builtin/system libs), but
it's a simple first step.

We shouldn't presume that future compilers will not have false positives or
find new occurrences of this warning, which would break compiling old versions
of the engine without passing custom `CXXFLAGS`.
Follow-up to #60652.
