Compose Multiplatform

Library mod bundling JetBrains' Compose Multiplatform libs. This is used in Polyfrost's [OneConfig](https://modrinth.com/mod/oneconfig) on modern versions of Minecraft. Uses our fork of [skiko](https://github.com/Polyfrost/skiko) temporarily to support Vulkan on 26.2 Note: this does NOT provide the functionality plugging in Compose into Minecraft. This is a separate library due to the sheer size of Compose's libraries, including Skiko.
