This commit removes the `LIBOMPTARGET_SHARED_MEMORY_SIZE` envar and
outputs a runtime warning if it is defined. Access to dynamic shared memory
should be obtained through the `dyn_groupprivate` clause (OpenMP 6.1) or
the launch arguments in liboffload kernel launch.
* Add compatibility support for DP and REPORT macros
* Define a set of predefined Debug Type for libomptarget
* Start to update libomptarget files (OffloadRTL.cpp, device.cpp)
This PR introduces new debug macros that allow a more fined control of
which debug message to output and introduce C++ stream style for debug
messages.
Changing existing messages (except a few that I changed for testing)
will come in subsequent PRs.
I also think that we should make debug enabling OpenMP agnostic but, for
now, I prioritized maintaing the current libomptarget behavior for now,
and we might need more changes further down the line as we we decouple
libomptarget.
The following patch introduces a new interop interface implementation
with the following characteristics:
* It supports the new 6.0 prefer_type specification
* It supports both explicit objects (from interop constructs) and
implicit objects (from variant calls).
* Implements a per-thread reuse mechanism for implicit objects to reduce
overheads.
* It provides a plugin interface that allows selecting the supported
interop types, and managing all the backend related interop operations
(init, sync, ...).
* It enables cooperation with the OpenMP runtime to allow progress on
OpenMP synchronizations.
* It cleanups some vendor/fr_id mismatchs from the current query
routines.
* It supports extension to define interop callbacks for library cleanup.
