  [flang][OpenMP] Use OmpDirectiveSpecification in ALLOCATE

The ALLOCATE directive has two forms:
- A declarative form with a standalone directive:
    !$OMP ALLOCATE (variable-list-item...)
- An executable form that consists of several diretives followed by an
  ALLOCATE statement:
    !$OMP ALLOCATE (variable-list-item...)
    !$OMP ALLOCATE (variable-list-item...)
    ...
    ALLOCATE (...)

The second form was deprecated in OpenMP 5.2 in favor of the ALLOCATORS
construct.

Since in the parse tree every type corresponding to a directive only
corresponds to a single directive, the executable form is represented by
a sequence of nested OmpAlocateDirectives, e.g.
   !$OMP ALLOCATE(x)
   !$OMP ALLOCATE(y)
   ALLOCATE(x, y)
will become
   OmpAllocateDirective
   |- ALLOCATE(x)            // begin directive
   `- OmpAllocateDirective   // block
      |- ALLOCATE(y)            // begin directive
      `- ALLOCATE(x, y)         // block

With this change all AST nodes for directives use OmpDirectiveSpecification
as the directive representation.
