Might not be ready for merge

The goal of this PR is to allow players to use Quilt Loader + QSL alongside Optifabric without causing any additional issues compared to using Fabric Loader + Fabric API.

closes #751 and #899

Note: I will be calling Quilt Standard Libraries/Quilted Fabric API the same since, although they are different repos, there exists a single mod implementation.

I tested the following versions with Quilt Loader 0.17.11 and 0.18.3 and I haven't encountered any issues:

• 1.19.3 + QSL 4.0.0 + I2_pre5
• 1.19.2 + QSL 3.0.0 + H9
• 1.18.2 + QSL 1.1.0 + H7
• 1.16.5 + FAPI 0.42.0 + G7
• 1.16.1 + FAPI 0.18.0 + G2

The versions in italics seem to start extremely slowly when using Quilt Loader 0.17.* or 0.16.1. I have not tested all of the loader versions, however it seems the startup is painfully slow on anything <0.18.
QSL exists only for versions >=1.18.2

Overcoming issues

1. Getting the game to start
   The main problem with running Optifabric on Quilt Loader was its reliance on deprecated internal Fabric Loader APIs. By checking if Quilt is present and, if so, not using those internal APIs, this issue can be easily circumvented, allowing the game to start normally.

2. Getting Quilt Standard Libraries to work
   QSL makes use mostly of Fabric API mixins, so there aren't many issues to fix (in theory at least).

• QSL Screen replaces Fabric's Screen API and as such its GameRendererMixin requires its own InterceptingMixin due to slightly different onBeforeRenderScreen and onAfterRenderScreen callback injectors.
• QSL's Item Extension API gets messed up by Optifine changing all instances of ItemStack.isOf(Items.CROSSBOW) to instanceof CrossbowItem inside the renderFirstPersonItem method. HeldItemRendererFix replaces the Optifine method with the vanilla one and re-adds Optifine's check Shaders.isSkipRenderHand at the head of the method. As far as I noticed, Optifine doesn't add any other behavioural changes. HeldItemRendererFix will run whether or not QSL is present at runtime.
• When checking the version of a Fabric API mod fabric-x the version of quilted_fabric_x will be returned instead. As such, OptifabricSetup will explicitly check if the quilted version of the mod is present, without checking the version, because even the lowest QSL mod version is based on a Fabric API version whose modules satisfy every version check in OptifabricSetup
