[Fix] (MG_Impl/EGLImpl, MG_Backend): handle EGL current handoff for NeoForge earlydisplay

Browse Source 
Treat valid-display no-surface eglMakeCurrent calls as EGL release requests, keep EGLState and backend current records consistent across threads, and rebind the native DirectGLES EGL context during attach/release.

Add EGLState coverage for cross-thread owner transfer and same-thread release/reattach behavior.
