[Feat] (DirectGLES): implement GL_ANY_SAMPLES_PASSED occlusion queries

Browse Source 
DirectGLES never registered BeginOcclusionQuery/EndOcclusionQuery, so
the frontend rejected the occlusion query targets entirely; the CTS
tests that use them (e.g. packed_depth_stencil.verify_partial/mixed_
attachments) left a stray GL_INVALID_ENUM that a later, unrelated
glGetError() check would report as its own failure
("Uploading buffer data failed" at gluDrawUtil.cpp:363).

Occlusion queries are core ES3 (glGenQueries/glBeginQuery(GL_ANY_
SAMPLES_PASSED, ...)/glEndQuery/glGetQueryObjectuiv), unlike the timer
queries which need GL_EXT_disjoint_timer_query, so they're wired up
unconditionally (independent of MOBILEGL_DISABLE_TIMERQUERY) using the
same handle-based GetQueryResult64/DeleteBackendQuery plumbing already
shared with timer queries. GetQueryResult64 now reads the 0/1 result
through the core 32-bit glGetQueryObjectuiv getter for occlusion
handles instead of the timer-only 64-bit GL_EXT_disjoint_timer_query
getter, since a driver can fully support core occlusion queries while
lacking that extension entirely.
