  [clang][OpenMP] Add AST nodes for opaque block/loop directives

Add two new AST nodes:
1. `OMPOpaqueBlockDirective` representing an executable directive
not associated with a loop, and
2. `OMPOpaqueLoopDirective` representing an executable directive
associated with a loop.

This is an indermediate step towards treating compound directives as
a sequece of either leaf or composite directives. The break-up of
compound directives into these constituents may be impossible in a
template, since the identity of objects referenced in clauses may
be impossible to establish.
When an executable directive is encountered in a function template, it
will be represented by one of the new AST nodes, depending on its
association. When the template is instantiated, these AST nodes will
replaced with the AST nodes used in non-templates.

  [clang][OpenMP] Prototype #2 of directive splitting

This is proto #1 minus the introduction of opaque AST nodes.

This isn't 100% finished, but it should be enough to illustrate
the changes needed to implement the feature.

Proto #1: https://github.com/llvm/llvm-project/pull/108855
