  [MLIR][OpenMP] Automate operand structure definition

This patch adds the "gen-openmp-clause-ops" `mlir-tblgen` generator to produce
the structure definitions previously in OpenMPClauseOperands.h automatically
from the information contained in OpenMPOps.td and OpenMPClauses.td.

Changes introduced to the `ElementsAttrBase` common tablegen class, as well as
some of its subclasses, add more fine-grained information on their shape and
type of their elements. This information is needed in order to properly
generate the corresponding types to represent these attributes within the
produced operand structures.

The original header is maintained to enable the definition of similar
structures that are not directly related to any single `OpenMP_Clause` or
`OpenMP_Op` tablegen definition.
