Arman Uguray	4f445c2e0a	[vello_shaders] Provide workgroup shared memory allocation sizes ... Naga traslates workgroup variable declarations to threadgroup address-space entry-point parameters when generating MSL. Metal API validation requires that the memory sizes for these parameters be set explicitly by calling setThreadgroupMemoryLength:index on the MTLComputeCommandEncoder. The crate now calculates the required memory size for global workgroup variables that are accessed by the entry point and provides them alongside the binding list. This is abstracted separately from the binding list. While the current usage that we're aware of is limited to Metal, this information is being provided as part of the generic ComputeShader type instead of a MSL-specific type, as the information itself is computed from the parsed WGSL IR and not specific to Metal.	2023-03-29 10:38:10 -07:00
