The Intel workaround sscanf'd "Build %d.%d.%d.%d" against glGetString(GL_VERSION),
which reads like "4.5.0 - Build 26.20.100.7870" - sscanf literals have to match
from the start, so it never returned 4 and HasIntelDualSrcBug was never consulted.
It's been inert since it was written, and the drivers it targeted are long gone.
Removing it orphaned the two helpers, so those go too.
Separately, when gl3stubInit() fails we left ver[0] at 3 while clearing GLES3.
Extension enumeration keys off the version, not the flag, so it went on to call
glGetStringi - one of the very entry points whose absence makes gl3stubInit()
fail. Drop back to 2.0 on that path, like the branch above it already does, and
null-check what glGetStringi hands back.

Add detection for GL_EXT_disjoint_timer_query (OpenGL ES) and
GL_ARB_timer_query (desktop GL) extensions. These extensions provide
GPU timestamp queries for profiling render pass durations.
Also adds function pointer declarations for glQueryCounter,
glGetQueryObjecti64v, and glGetQueryObjectui64v.

The original code checked for "Mali" in GL_RENDERER and disabled GLES3
for all Mali GPUs, which was a workaround for bugs in ARM's proprietary
Mali driver. However, Mesa/Panfrost (open-source Mali driver) does not
have these bugs and should be allowed to use GLES3.
This patch:
- Adds GPU_VENDOR_MESA for identifying Mesa drivers via GL_VENDOR
- Changes the GLES3 ban to only apply when GL_VENDOR="ARM" (proprietary)
- Allows Mesa/Panfrost Mali GPUs to use GLES3 features
Expected behavior:
- ARM proprietary driver (GL_VENDOR="ARM"): GLES3 disabled (preserved)
- Mesa/Panfrost (GL_VENDOR="Mesa"): GLES3 enabled
- Other Mesa drivers: Unaffected

* Rename LogType to Log
* Explicitly use the Log:: enum when logging. Allows for autocomplete when editing.
* Mac/ARM64 buildfix
* Do the same with the hle result log macros
* Rename the log names to mixed case while at it.
* iOS buildfix
* Qt buildfix attempt, ARM32 buildfix
GL_COMPRESSED_RGBA_ASTC_4x4_KHR is not defined and looks to be an OpenGL ES 3.0 extension.
This fixes building on the Raspberry Pi 1-3 using VideoCore IV OpenGL ES 2.0 headers.
