Libomptarget grew out of a project that was originally not in LLVM. As
we develop libomptarget this has led to an increasingly large clash
between the naming conventions used. This patch fixes most of the
variable names that did not confrom to the LLVM standard, that is
`VariableName` for variables and `functionName` for functions.
This patch was primarily done using my editor's linting messages, if
there are any issues I missed arising from the automation let me know.

We used to globally include the libomptarget include directory for all
projects. This caused some conflicts with the other files named
"Debug.h". This patch changes the cmake to include these files via the
target include instead.

The hand-rolled linking logic in elf_common does not account for
the possibility of using LLVM dylib rather than a dozen static
libraries. Since it does not seem to be easily convertible
to add_llvm_library, just hand-roll support for LLVM_LINK_LLVM_DYLIB.
This is necessary to support stand-alone builds against installed LLVM.

This change-set removes libelf usage from elf_common part of the plugins.
libelf is still used in x86_64 generic plugin code and in some plugins
(e.g. amdgpu) - these will have to be cleaned up in separate checkins.

Summary:
The allocator interface added in D97883 allows the RTL to allocate shared and
host-pinned memory from the cuda plugin. This patch adds support for these to
the runtime.

Constant static data member can be defined in the class without another
define after the class in C++17. Although it is C++17, Clang can still handle it
even w/o the flag for C++17. Unluckily, GCC cannot handle that.

The lifetime of `libomptarget` and its opened plugins are not aligned
and it's hard for `libomptarget` to determine when the plugins are destroyed.
As a result, some issues (see D94256 for details) occur on some platforms.
Actually, if we take target memory as target resources, same as other resources,
such as CUDA streams, in each plugin, then the memory manager should also be in
the plugin. Also considering some platforms may want to opt out the feature, it
makes sense to move the memory manager to plugin, make it a common interface, and
let plguin developers determine whether they need it. This is what this patch does.
CUDA plugin is taken as example to show how to integrate it. In this way, we can
also get a bonus that different thresholds can be set for different platforms.

For now `elf_common.c` is taken as a common part included into
different plugin implementations directly via
`#include "../../common/elf_common.c"`, which is not a best practice. Since it
is simple enough such that we don't need to create a real library for it, we just
take it as a interface library so that other targets can link it directly. Another
advantage of this method is, we don't need to add the folder into header search
path which can potentially pollute the search path.
VE and AMD platforms have not been tested because I don't have target machines.

This patch consolidates the error handling and messaging routines to a single

This patch adds a libomptarget plugin for the NEC SX-Aurora TSUBASA Vector
Engine (VE target). The code is largely based on the existing generic-elf
plugin and uses the NEC VEO and VEOSINFO libraries for offloading.

to reflect the new license. These used slightly different spellings that
defeated my regular expressions.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.
