[Backport to 14] [SPIR-V 1.1/1.2] SPIRVReader: Add SubgroupsPerWorkgroup(Id) (#2916) (#2929) Add support for consuming the SubgroupsPerWorkgroup (SPIR-V 1.1) and SubgroupsPerWorkgroupId (SPIR-V 1.2) execution modes. Map both of these to `spirv.ExecutionMode` named metadata. (cherry picked from commit 98cd3e46bd62bd0e798a3c557f2ce2fe99bb51c9)
