This fixes a compile-time error recently introduced within the remote
offloading plugin. This patch also removes some extra linker flags that are unnecessary, and adds an explicit abseil linker flag without which we occasionally get problems.

D97883 introduced a compile-time error in the experimental remote offloading
libomptarget plugin, this patch fixes it and resolves a number of
inconsistencies in the plugin as well:
1. Non-functional Asynchronous API
2. Unnecessarily verbose debug printing
3. Misc. code clean ups
This is not intended to make any functional changes to the plugin.

This introduces a remote offloading plugin for libomptarget. This
implementation relies on gRPC and protobuf, so this library will only
build if both libraries are available on the system. The corresponding
server is compiled to `openmp-offloading-server`.
This is a large change, but the only way to split this up is into RTL/server
but I fear that could introduce an inconsistency amongst them.
Ideally, tests for this should be added to the current ones that but that is
problematic for at least one reason. Given that libomptarget registers plugin
on a first-come-first-serve basis, if we wanted to offload onto a local x86
through a different process, then we'd have to either re-order the plugin list
in `rtl.cpp` (which is what I did locally for testing) or find a better
solution for runtime plugin registration in libomptarget.
