  Remove redundant linalg.matmul_signed (#98615)

`linalg.matmul` already has an attribute for casts, defaults to signed
but allowed unsigned, so the operation `linalg.matmul_unsigned` is
redundant. The generalization test has an example on how to lower to
unsigned matmul in linalg.

This is the first PR in a list of many that will simplify the linalg
operations by using similar attributes.
