Use new production=yes option#22
Conversation
Equivalent to debug_symbols=no use_lto=yes use_static_cpp=yes. We keep LTO disabled for iOS as users need to relink on deploy, and that's very slow and memory hungry with LTO.

@naithar 3.2.4 RC 2 used this with OPTIONS="production=yes" only.
I guess this change should fix godotengine/godot#46064.

What about -flto=thin, it should be supported and work much faster.

We could try it, though that requires changes to platform/iphone/detect.py. Might also be worth reworking how we pass LTO options as e.g. for -flto=thin on Linux you need to pass use_lto=yes use_lld=yes use_thinlto=yes.

It was 3x faster for tvOS builds #21, so we can try using it. I can still provide macOS based non-lto builds just in case.
@akien-mga should I also change tvOS build script to support production flag?

Yeah, sounds good.

And it's using much less memory (under 900 MB), waiting for a few minutes for release builds seems pretty reasonable.

Also, LTO flags are completely missing from macOS detect.py.

Yeah I think we should overhaul the LTO flags to make sure they're consistent across all platforms and use the most optimal configuration by default (so thin on Clang/LLD).

I opened godotengine/godot#46317 to continue the discussion on LTO for iOS and macOS.

I had a small doubt whether this override would work... and it turns out it didn't :)
Needs some fixes to how we handle overriding options that would get default values from dev=yes and production=yes: godotengine/godot#46365
