Summary:
This is modeled after the clang and llvm lit tests.
Several properties have CMAKE_CFG_INTDIR as part of the path - this works correctly when the cmake generator only supports one configuration which is known at configuration time, but it does not work correctly when the cmake generator supports multiple configurations (for example, VS).
For VS, CMAKE_CFG_INTDIR ends up set as $Configuration and then it is never updated correctly. Instead, the lit configuration can use a property that can be overwritten at run time. AddLLVM does that for several properties (such as LLVM_TOOLS_DIR).
This change is also removing properties from the lit/CMakeLists.txt that are actually set during the call to configure_lit_site_cfg

The HAVE_LIBZ variable is not exported by LLVM, and therefore is not
available in stand-alone builds of other tools. Use LLVM_ENABLE_ZLIB
which is the name under which the effective value is exported.
Additional, use llvm_canonicalize_cmake_booleans() to make sure that
a correct (Python-safe) boolean value is passed down to lit.

Summary:
We use the llvm decompressor to decompress SHF_COMPRESSED sections. This enables
us to read data from debug info sections, which are sometimes compressed,
particuarly in the split-dwarf case. This functionality is only available if
llvm is compiled with zlib support.

Summary:
Using the in-tree clang should be the default test configuration as that
is the one compiler that we can be sure everyone has (better
reproducibility of test results). Also, it should hopefully reduce the
impact of pr35040.
This also reduces the number of settings which control the compiler
used. LLDB_TEST_C_COMPILER is used for C files and
LLDB_TEST_CXX_COMPILER for C++ files. Both of the settings default to
the in-tree clang.

Use both LLDB- and LLVM-specific tool/library directories when LLDB is
being built stand-alone. This ensures that the freshly-built tools
(and libraries) are used correctly.
Without this patch, the test suite uses LLVM_TOOLS_DIR and LLVM_LIBS_DIR
to locate lldb, and set PATH and LD_LIBRARY_PATH. When doing
a stand-alone build, these variables represent the installed LLVM.
As a result, tests either fail due to missing lldb executable
or use an earlier installed LLDB version rather than the one being
built.
To solve this, additional LLDB_TOOLS_DIR and LLDB_LIBS_DIR variables
are added and populated using LLVM_*_OUTPUT_INTDIR. Those variables
contain directories used to output built executables and libraries.
In stand-alone builds, they represent the build-tree directories
used by LLDB. In integrated builds, they have the same values as
LLVM_*_DIR and therefore using them does not harm.
The new variables are prepended to PATH and LD_LIBRARY_PATH to ensure
that freshly built binaries are preferred over potentially earlier
installed ones. Furthermore, paths used to locate various tools are
updated to match appropriate locations.

Summary:
This patch supplies basic infrastructure for LLDB to use LIT, and ports a few basic test cases from the LLDB test suite into LIT.
With this patch the LLDB lit system is not capable or intended to fully replace the existing LLDB test suite, but this first patch enables people to write lit tests for LLDB.
The lit substitution for %cc and %cxx default to the host compiler unless the CMake option LLDB_TEST_CLANG is On, in which case the in-tree clang will be used.
The target check-lldb-lit will run all lit tests including the lit-based executor for the unit tests. Alternatively there is a target generated for each subdirectory under the lit directory, so check-lldb-unit and check-lldb-expr will run just the tests under their respective directories.
The ported tests are not removed from the existing suite, and should not be until such a time when the lit runner is mature and in use by bots and workflows.

At the moment almost every lit.site.cfg.in contains two lines comment:
## Autogenerated by LLVM/Clang configuration.
# Do not edit!
The patch adds variable LIT_SITE_CFG_IN_HEADER, that is replaced from
configure_lit_site_cfg with the note and some useful information.
