When hwloc is used and is installed outside of the default paths, the omp CMake target
needs to provide the needed include path thru the CMake target by adding it with
target_include_directories to it, so libompd gets it as well when it defines it's cmake
target using target_link_libraries.

This is the original patch in my GNUInstallDirs series, now last to merge as the final piece!
It arose as a new draft of D28234. I initially did the unorthodox thing of pushing to that when I wasn't the original author, but since I ended up
- Using `GNUInstallDirs`, rather than mimicking it, as the original author was hesitant to do but others requested.
- Converting all the packages, not just LLVM, effecting many more projects than LLVM itself.
I figured it was time to make a new revision.
I have used this patch series (and many back-ports) as the basis of https://github.com/NixOS/nixpkgs/pull/111487 for my distro (NixOS), which was merged last spring (2021). It looked like people were generally on board in D28234, but I make note of this here in case extra motivation is useful.
---
As pointed out in the original issue, a central tension is that LLVM already has some partial support for these sorts of things. Variables like `COMPILER_RT_INSTALL_PATH` have already been dealt with. Variables like `LLVM_LIBDIR_SUFFIX` however, will require further work, so that we may use `CMAKE_INSTALL_LIBDIR`.
These remaining items will be addressed in further patches. What is here is now rote and so we should get it out of the way before dealing more intricately with the remainder.

OPENMP_INSTALL_LIBDIR is set to the installation path of shared and static
libompd.This should avoid the mixing of 32 and 64 bit on same path in
multi-lib set-up.

This is a continuation of the review: https://reviews.llvm.org/D100181
Creates a new directory "libompd" under openmp.
"TargetValue" provides operational access to the OpenMP runtime memory
for OMPD APIs.
With TargetValue, using "pointer" a user can do multiple operations
from casting, dereferencing to accessing an element for structure.
The member functions are designed to concatenate the operations that
are needed to access values from structures.
e.g., _a[6]->_b._c would read like :
TValue(ctx, "_a").cast("A",2)
.getArrayElement(6).access("_b").cast("B").access("_c")
For example:
If you have a pointer "ThreadHandle" of a running program then you can
access/retrieve "threadID" from the memory using TargetValue as below.
TValue(context, thread_handle->th) /*__kmp_threads[t]->th*/
.cast("kmp_base_info_t")
.access("th_info") /*__kmp_threads[t]->th.th_info*/
.cast("kmp_desc_t")
.access("ds") /*__kmp_threads[t]->th.th_info.ds*/
.cast("kmp_desc_base_t")
.access("ds_thread") /*__kmp_threads[t]->th.th_info.ds.ds_thread*/
.cast("kmp_thread_t")
.getRawValue(thread_id, 1);
