[wgsl] Support `subgroupMatrixLoad` and `subgroupMatrixStore` with `i8` and `u8`

This patch adds the overloads of `subgroupMatrixLoad` and
`subgroupMatrixStore` with `i8` and `u8` as the element types of the
subgroup matrices.

This patch also fixes the template of the subgroup matrix tests about
`i8` and `u8` by replacing all `array<i8>` with `array<i32>` and
replacing `array<u8>` with `array<u32>`.
