[UR][CUDA][HIP] Replace ur::assertion with UR_CHECK_ERROR (#10986)

Lots of hip/cu driver API calls were wrapped in `ur::assertion(res ==
CU_SUCCESS)` etc which:

- Means that any native error messages returned from the affected driver
api calls were lost.
- Since these APIs report errors asynchronously, such that they are
thrown from the last API call rather than the call which led to the
error, previous asynchronous error messages from different APIs to the
ones wrapped by the `ur::assertion` could also be lost depending on user
code.

These problems are fixed by swapping these assertions with
`UR_CHECK_ERROR`.

Note that in the future UR may want to adjust `UR_CHECK_ERROR` so that
it throws `UR_RESULT_ERROR_ADAPTER_SPECIFIC` etc instead of using
`std::cerr` etc to report the error etc. But I think it makes sense to
still use `UR_CHECK_ERROR` to wrap driver API calls because it means
that the __LINE__, __FUNCTION__ etc info can be correctly passed to
native error reporting.
