Nothing has generated or used a geometry shader since the GS paths were removed
- GeometryShaderGenerator is gone, and ShaderWriter's BeginGSMain/EndGSMain had
no callers at all. Removes ShaderStage::Geometry and everything hanging off it:
the GS preambles and GSMain helpers in ShaderWriter, the stage mappings in all
three thin3d backends, the D3D11 geometry shader plumbing (curGS_, the pipeline
and module members, gs_4_0 compilation), CreateGeometryShaderD3D11, the unused
PipelineFlags::USES_GEOMETRY_SHADER and PipelineManagerVulkan's
UsesGeometryShader().
Also stop enabling the Vulkan geometryShader device feature, since we no longer
have any use for it.
Kept on purpose: the device feature is still listed in the feature dumps (like
other capabilities we don't use), and the Vulkan shader cache header keeps its
now-always-zero geometry shader count so the on-disk format stays compatible.
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.

Reported by Joseph on Discord.
Sometimes, things could align perfectly so allocations happend exactly
at the end of a pushbuffer. At the same time, we allow our vertex decoder to write an extra few
bytes if it needs to for speed. Unfortunately I missed this interaction,
resulting in some uncommon crashes that were especially common with
heavy-geometry things like modified GTA LCS with PS2 assets, for
example.
The problem was reported with Vulkan, but our OpenGL backend had the
same issue too.
* 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
