Improvements to align CTS and Spec for Device:

- Rework urDeviceGetInfoTest to move all enums to their own tests instead of a switch case - #2290
- Remove the UR/OpenCL Device enum map function - no point maintaining both a switch case and a separate mapping function
- Update some spec wording for consistency
- Add missing Device info enums to OpenCL adapater
- Add new urDevicePartition test for checking UR_DEVICE_INFO_PARENT_DEVICE
- Move UUR_RETURN_ON_FATAL_FAILURE and UUR_ASSERT_SUCCESS_OR_UNSUPPORTED to join similar macros in checks.h
- Update spec to say info queries that return char[] are null-terminated
- Update UR_DEVICE_INFO_MAX_IMAGE_LINEAR_WIDTH/HEIGHT/PITCH should be uint32_t, matching SYCL RT
- Add missing unsupported device enums to HIP adapter

Addressed feedback:
- Reverted bindless image types back to size_t
- Moved ComponentDevices test to a separate PlatformTest derived fixture
- Added new ASSERT_GET_INFO macro as a helper to validate simple numerical GetInfo queries
- Added new stringPropertyIsValid helper function to validate string queries
