Add a separate binding-point model to VertexArrayObject with eager
resolution into the flat per-attribute view backends already consume.
Implements glBindVertexBuffer(s), glVertexAttrib(I)Format,
glVertexAttribBinding, glVertexBindingDivisor and the DSA variants
(glVertexArrayAttribBinding, glVertexArrayBindingDivisor,
glVertexArrayVertexBuffers), fixing glVertexArrayVertexBuffer which
previously conflated binding index with attribute index. Multi-bind
(glBindBuffersBase/Range) loops over the single-bind entry points.
Needed by Flywheel's indirect backend (GlVertexArrayDSA setup path).

Track context generation + synced change serial per resource; re-register
ops on MakeCurrent. Fixes frozen buffer contents after the trace replayer's
probe context teardown.

Replace the application-specific PackPhotonSharedVec3Memory GLSL regex
patch with a general DecomposeWorkgroupVec3Pass SPIR-V optimization pass.
The new pass decomposes vec3/ivec3/uvec3/bvec3 Workgroup (shared) memory
variables into scalar arrays (e.g. shared vec3 arr[N][M] -> shared float
arr[N][M][3]), rewriting whole-vector loads/stores into per-component
scalar loads/stores. Component-level accesses (e.g. arr[i].x) are
unchanged since a trailing component index into a float[3] yields the
same scalar pointer as it did for a vec3.
Unlike the regex hack, the pass is application-agnostic: it does not
match on variable names, array dimensions, or shader pack identity, and
runs at the SPIR-V level before SPIRV-Cross decompilation.
Registered in SanitizeAndOptimizeBinary after AggressiveDCE so dead
workgroup accesses are already eliminated. Asserts on unsupported
OpAtomic*/OpCopyMemory targeting vec3 workgroup pointers.
Adds ProgramUtilTest.DecomposeWorkgroupVec3InSpirvPass covering array
declaration, +=, whole load/store, component access, and row-copy loop.
