[Feat] (MG_Impl, MG_State, MG_Util): the GL_KHR_parallel_shader_compile surface (P1 stage 5)

Browse Source 
GL_COMPLETION_STATUS_KHR in both object getters, reading the non-joining
node-direct state - the one query that must never block is asserted never
to reach a join gate. glMaxShaderCompilerThreadsKHR/ARB share one
implementation: a zero count suspends async FIRST and then joins every
outstanding compile and link this context owns (suspend-before-join is the
only order whose post-condition is 'nothing in flight'), a nonzero count
restores; the suspension is a process latch the extension controls, kept
distinct from the configuration flag that gates the ADVERTISEMENT - an app
that turned threading off has not made the extension disappear.
GL_MAX_SHADER_COMPILER_THREADS_KHR reports the thread count. DriverPost
gains the MobileGL-side async row (PASS/INFO naming the env knob) and an
informational host-driver row backed by a new GLES capability probe.

The extension string itself lands per backend in the two follow-up
commits, keeping this one green stand-alone.
