Build under Linux broken for UR due to L0 dependency

[Alexandr-Konovalov]

Describe the bug

Build broken after
rm -rf build
python3 $DPCPP_HOME/llvm/buildbot/configure.py -t Debug
python3 $DPCPP_HOME/llvm/buildbot/compile.py

In configure log I see

-- Checking for module 'level-zero>=1.24.2'
--   Package dependency requirement 'level-zero >= 1.24.2' could not be satisfied.
Package 'level-zero' has version '1.20.3', required version is '>= 1.24.2'
-- Level Zero Adapter: Download Level Zero loader and headers from github.com
-- Level Zero Adapter: Will fetch Level Zero Loader from https://github.com/oneapi-src/level-zero.git

I don't see ze_structure_type_ext_t in Level Zero Loader GitHub etc.

The build was broken by [UR] Update compute-runtime tag 19986

[pbalcer]

I'm not sure if this is a regression after #19986. I can't reproduce this on my system:

-- Fetching sparse source level_zero/include from https://github.com/intel/compute-runtime.git 25.05.32567.17
-- Using Level Zero include headers from /home/pbalcer/llvm/build/content-exp-headers/level_zero/include
-- Level Zero Adapter: Using Level Zero headers from /home/pbalcer/llvm/build/content-exp-headers/level_zero/include
-- Will fetch Unified Memory Framework from https://github.com/oneapi-src/unified-memory-framework.git

This isn't a new problem, what changed is that we now require a newer version of the headers than what's installed in your system. As a workaround, you could remove them from your system. These are not level-zero headers, but driver headers that contain definitions for experimental features.

Searching for OS-installed driver header needs a version check.

[Alexandr-Konovalov]

Thank you, that is my situation and the workaround helps.
