Compilation Error: Use of Undeclared Identifier 'MTLGPUFamilyApple7' and 'MTLGPUFamilyApple6'

[iabheejit]

I'm encountering compilation errors when trying to build whisper.cpp on macOS. The errors are related to the use of undeclared identifiers MTLGPUFamilyApple7 and MTLGPUFamilyApple6 in the ggml-metal.m file.

Expected Behavior: The project should compile successfully without any errors.

Actual Behavior: The following errors are encountered during compilation:
