Revert "Remove stale expectations after manual retesting"

This reverts commit afa9b1e343b1d90c9e9ff40da52c663c9751ab6b.

Reason for revert: CQ failures. 

Original change's description:
> Remove stale expectations after manual retesting
>
> I manually retested the following tests on Windows 11 with
> - NVDIA RTX 4070
> - Intel xe-lpg (Intel Arc, ID 0x7d55)
>
> In Chrome 143 (stable) and 145 (canary).
>
> Both with:
> - DXC (the default)
> - FXC (--disable-dawn-features=use_dxc)
>
> These all passed:
> webgpu:shader,execution,expression,binary,af_matrix_addition:*
> webgpu:shader,execution,expression,binary,af_matrix_subtraction:*
> webgpu:shader,execution,expression,binary,af_matrix_scalar_multiplication:*
>
