Deps: Update rapidyaml to v0.11.1 and move out of tree

[chaoticgd]

Description of Changes

Update rapidyaml to v0.11.1, and move it out of tree.

Rationale behind Changes

I was asked to help with updating this.

With this update the API for error handling has changed, so it required some changes in common/YAML.cpp.

I've made it so that RapidYAML is built using the dependencies build scripts since the existing build setup we had made it annoying to update. We were using our own custom build scripts since we needed it to be buildable with MSBuild as well as CMake. RapidYAML's code relies on multiple levels of submodules for its dependencies, so this made figuring out what files we needed confusing.

Packagers will need to add RapidYAML as a dependency of PCSX2 (v0.10.0 should still work).

Suggested Testing Steps

Try loading folder memory cards and the game DB. Try corrupting these YAML files and seeing if the error message is as expected. Test on Windows.

Did you use AI to help find, test, or implement this issue or feature?

No.

Update: I want to try to build this with the dependencies build script instead

In that case, would you mind keeping the old callback code in with a #if RYML_VERSION_MAJOR > 0 || RYML_VERSION_MINOR >= 11? Due to the API breaks, Fedora won't be updating to 0.11 until F44 and I'd rather not have to keep patching my local tree.

I think I'll wait for some of the existing deps PRs to go in. So I need to do less rebasing.
