[ORC] Re-land https://github.com/llvm/llvm-project/pull/81826
This patch adds two plugins: VTuneSupportPlugin.cpp and
JITLoaderVTune.cpp. The testing is done in a manner similar to
llvm-jitlistener. Currently, we only support the old version of Intel
VTune API.

Allow C-API users to debug their JITed code via the GDB JIT Interface.
This is currently supported on ELF and MachO based platforms. On
other systems `LLVMOrcLLJITEnableDebugSupport()` returns an error.
This patch adds a new C-API header `LLJITUtils.h`, which can host
further advanced JIT features in the future. Using the header requires
linking against LLVMOrcDebugging.
This re-applies db51e572893, which was reverted in 05b1a2cb3e6 due to bot
failures. The DebuggerSupportPlugin now depends on DWARF, so it has been moved
to the new OrcDebugging library (as has the enableDebuggerSupport API).
This patch adds line numbers to perf jitdump records emitted by the
PerfSupportPlugin, by parsing and using a DWARFContext from preserved debug
sections.
To avoid making the OrcJIT library depend on DebugInfoDWARF this patch
introduces a new OrcDebugging library.
