Since we can now build the DeviceRTL with SPIR-V, redo the
`XFAIL/UNSUPPORTED` specifications for the tests we see passing/failing
on the Level Zero backend with the DeviceRTL being used.
The tests marked `UNSUPPORTED` hang or sporadically fail and those are
tracked in https://github.com/llvm/llvm-project/issues/182119.
This change will allow us to enable CI testing with the DeviceRTL.
Here are the full test results with this change applied, running only
the `spirv64-intel` `check-offload` tests:
```
Total Discovered Tests: 453
Unsupported : 206 (45.47%)
Passed : 141 (31.13%)
Expectedly Failed: 106 (23.40%)
```
31% is not a bad start.

We finally got our buildbot added (to staging, at least) so we want to
start running L0 tests in CI.
We need `check-offload` to pass though, so XFAIL everything failing.
There's a couple `UNSUPPORTED` as well, those are for sporadic fails.
Also make set the `gpu` and `intelgpu` LIT variables when testing the
`spirv64-intel` triple.
We have no DeviceRTL yet so basically everything fails, but we manage to
get
```
Total Discovered Tests: 432
Unsupported : 169 (39.12%)
Passed : 67 (15.51%)
Expectedly Failed: 196 (45.37%)
```
We still don't build the level zero plugin by default and these tests
don't run unless the plugin was built, so this has no effect on most
builds.

Many tests in the `offload` project have requirements defined by which
targets are not supported rather than which platforms are supported.
This patch aims to streamline the requirement definitions by adding four
new feature tags: `host`, `gpu`, `amdgpu`, and `nvidiagpu`.
In a nutshell, this moves our libomptarget code to populate the offload
subproject.
With this commit, users need to enable the new LLVM/Offload subproject
as a runtime in their cmake configuration.
No further changes are expected for downstream code.
Tests and other components still depend on OpenMP and have also not been
renamed. The results below are for a build in which OpenMP and Offload
are enabled runtimes. In addition to the pure `git mv`, we needed to
adjust some CMake files. Nothing is intended to change semantics.
```
ninja check-offload
```
Works with the X86 and AMDGPU offload tests
```
ninja check-openmp
```
Still works but doesn't build offload tests anymore.
```
ls install/lib
```
Shows all expected libraries, incl.
- `libomptarget.devicertl.a`
- `libomptarget-nvptx-sm_90.bc`
- `libomptarget.rtl.amdgpu.so` -> `libomptarget.rtl.amdgpu.so.18git`
- `libomptarget.so` -> `libomptarget.so.18git`
Fixes: https://github.com/llvm/llvm-project/issues/75124
