[E2E] `Adapters/level_zero_eager_init.cpp` induces other tests to hang on Windows BMG with prebuilt E2E binaries

[ayylol]

Describe the bug

Running Adapters/level_zero_eager_init.cpp on Battlemage on windows with prebuilt E2E binaries flakily XPASSes, or induces other tests to hang. Verified on CI.

Runs prior to changing markup for Adapters/level_zero_eager_init.cpp could hang:

• https://github.com/intel/llvm/actions/runs/14476883669/job/40606429193

The E2E tests do not hang here, but Adapters/level_zero_eager_init.cpp reports as XPASS:

• https://github.com/intel/llvm/actions/runs/14480096620/job/40616327172

After removing the XFAIL from Adapters/level_zero_eager_init.cpp, a test hangs, and after disabling the hanging test a different test hangs:

• https://github.com/intel/llvm/actions/runs/14481582243/job/40620609360
• https://github.com/intel/llvm/actions/runs/14483077653/job/40624380817

After disabling the Adapters/level_zero_eager_init.cpp (instead of XFAILing) E2E tests pass without hanging:

• https://github.com/intel/llvm/actions/runs/14497224154/attempts/1
• https://github.com/intel/llvm/actions/runs/14497224154/attempts/2
• https://github.com/intel/llvm/actions/runs/14497224154/attempts/3
