[Feat] (MG_Util/SelfTest): grouped POST rows, merged probes, MobileGL-reported strings

Browse Source 
Rows in each backend section now sort FAIL -> WARN -> PASS -> INFO
(stable within groups), with identity strings always last: the device
strings renamed to 'Backend driver reported GL_*' and a new bottom
group 'MobileGL reported GL_VENDOR/GL_VERSION/GL_RENDERER/GL_EXTENSIONS'
showing exactly what MobileGL advertises to applications on that
backend, assembled from the same sources as GL_Getter and the backend
objects (extension-list construction extracted into shared helpers so
POST cannot drift from the real advertisement).

Rows probing the same subject are merged into single verdicts whose
details keep every sub-fact and causal chain: the six EGL setup steps
become one 'ES3 context' row, extension presence + functional probe
become one 'Timer queries' row per backend (including the
MOBILEGL_DISABLE_TIMERQUERY override explanation), and the Vulkan
loader/instance, surface-extension pair, and physical-device/queue/API
chains each collapse into one row.

Capability rows previously dumped as INFO now carry verdicts: index
type uint8 (WARN when absent - uint8 index buffers have no conversion
fallback), VK_KHR_draw_indirect_count (WARN when absent - count draws
degrade to CPU readback loops); buffer_storage/base_instance stay
honest INFO when absent since no MobileGL path degrades.
