[TOSA] Allow all integer types in most ops (#86509)
As discussed in one of the previous TOSA community meetings, we would
like to allow for more integer types in the TOSA dialect to enable more
use cases.
For strict standards conformance, the TosaValidation pass can be used.
Follow up PRs will extend conversions from TOSA where needed.
