[clang] [llvm] Enable LLDB tests in Linux pre-merge CI (PR #94208)

We have configured few buildbots for cross lldb tests with Windows x86_64, 
Linux x86_64 hosts and Linux Aarch64 targets. Our main setup is Windows host 
and currently it is 100% green. We still have a number of local patches. The 
biggest changes are related to Makefile.rules to build API tests with different 
tools and hosts and linking the correct libraries on Linux host. We also 
adapted Shell tests to run on a remote target. We will prepare PRs to mainline 
soon. We have fugured out that currently lldb does not support CXX ABI 2. Few 
tests are marked as XFAIL with unclear reasons and strange conditions, so we 
got few XPASS tests. Most failed API tests on Windows hosts were related to 
path separators. Currently SBFileSpec (FileSpec wrapper for python) does not 
have a constructor to pass tripple or style, so it is impossible to create a 
POSIX path in API tests on the Windows host. But FileSpec stores a normalized 
path and the path style is completelly ignored inside lldb code.

[clang] [llvm] Enable LLDB tests in pre-merge CI (PR #94208)

> First Windows CI results: LLDB unit tests do not even build.

Please note the following for Windows setup:

- We used cmake 3.25.3 because we got some issues with the latest cmake.
- python prerequisites are: `python -m pip install swig pexpect psutil`.
- Most gnu tools may be used from `git` distributive, PATH env must contain 
C:\Program Files\Git\usr\bin
- lldb API tests require `make` which can be installed via Chocolatey `choco 
install make`.
- lldb for Windows host must be compiled with 
`CMAKE_MSVC_RUNTIME_LIBRARY=MultiThreadedDLL` (or MultiThreadedDebugDLL in case 
of CMAKE_BUILD_TYPE=Debug), otherwise python and lldb will use different UCRT 
instances and python will crash with the exit code 0xC409 
(STATUS_STACK_BUFFER_OVERRUN) because of an assert in UCRT.
