[metal] Enable subgroup matrix feature

The feature is supported if the GPU family is Apple 7 or higher.

The two supported configurations are 8x8 matrices with f32 and f16
component types.

Add a Dawn E2E test that tests all supported matrix configurations for
`subgroupMatrixMultiply` and `subgroupMatrixMultiplyAccumulate`.
