[SYCL] Implement coverage instrumentation for device code

[0x12CC]

This PR reapplies the changes from #20206. It also includes the following new changes:

1. The coverage tools were moved from compiler dependencies to E2E test dependencies so that the SYCL toolchain can be be built without compiler-rt.
2. A definition of __sycl_increment_profile_counters was added to fix build errors when building with Apple Clang.

@steffenlarsen, @AlexeySachkov, could you please help review this updated PR. The new changes added to fix the post-commit failures are in 40f2af7 and 3d8fee6.

The two extra commits LGTM

@aelovikov-intel, could you please run the post-commit testing? I don't think I have the required permissions to create a new branch or manually run any workflow.

Please ping me once that finishes to remove the branch.

Thanks, @aelovikov-intel. It's done so you can delete the branch.

The only test failure is in the Windows build:

Failed Tests (1):
  SYCL-Unit :: scheduler/./SchedulerTests_Non_Preview_Tests.exe/10/59

This is the same failure as in the post-commit testing for 2b96dd3 so it shouldn't be related to these changes.
