  [libomp] Add kmp_str_ref (ADT 1/2)

libomp currently has two limitations:
1) although it's C++, it doesn't link against the C++ stdlib
2) it cannot link against the implementation of LLVM ADTs

These limitations shall not be altered at the moment.

As a result, this commit introduces kmp_str_ref, which is similar to
LLVM's StringRef. It currently only includes methods I need at the
moment, but it's easily extensible.

  [libomp] Add kmp_vector (ADT 2/2)

See rationale in the commit adding kmp_str_ref.

This commit introduces kmp_vector, a class intended primarily for small
vectors. It currently only includes methods I need at the moment, but
it's easily extensible.

  [libomp] OpenMP 6.0: Add device trait parser

OpenMP 6.0 introduced a device trait specification language for the
environment variables OMP_AVAILABLE_DEVICES (4.3.7) and
OMP_DEFAULT_DEVICE (4.3.8).

This commit defines a grammar for that language and implements a parser
for a large part of this grammar.
It also already does the parsing of OMP_DEFAULT_DEVICE, but in a
backward compatible manner, not yet exposing the new capabilities to the
user (this will come in a follow-up commit).
