BZLZHH 48dd1c5956 [Feat] (MG_State, MG_Impl): transform feedback state, validation and reflection

First stage of GL 3.0 transform feedback: glTransformFeedbackVaryings /
glGetTransformFeedbackVarying / glBeginTransformFeedback /
glEndTransformFeedback were unimplemented stubs. This adds

- per-program capture state: requested varyings apply on the next link and
  resolve against the last vertex-processing stage's linker objects (with
  gl_Position/gl_PointSize handled as builtins), failing the link on
  unknown or duplicate names or exceeded interleaved/separate limits, with
  offsets and strides computed per GL rules;
- context Begin/End state with the GL 3.3 error semantics: invalid
  primitive modes, redundant Begin/End, missing program or capture-buffer
  bindings, primitive-mode compatibility at draw time, and the
  while-active prohibitions on rebinding capture buffers, switching
  programs, and relinking the captured program;
- GetProgramiv TRANSFORM_FEEDBACK_* queries and a 4-slot bound on indexed
  GL_TRANSFORM_FEEDBACK_BUFFER binding points.

KHR-GL33.transform_feedback api_errors/linking_errors/get_xfb_varying now
pass; GPU-side capture is the remaining stage.

EGLImpl

[Refactor] (Lifecycle): own MobileGL's lifecycle from the EGL layer instead of ELF static ctor/dtor - the first EGL/WGL entry point lazily initializes via a thread-safe, re-init-capable EnsureInitialized (AutoInit is gone), the last eglTerminate with no initialized display and nothing current tears the whole library down deterministically inside the EGL lifecycle, and the global singletons move to leak-at-exit heap storage so process exit runs no backend destructors at all (AutoDestroy and the Windows DllMain abandon hook are gone); fixes the exit-time SIGABRT from undefined static-destruction order - the DirectGLES buffer-pool mutex abort on Android clean exits, and the pre-existing macOS QueryTest/ProgramTest 'Subprocess aborted' gtest failures now pass (ctest 411/411)
