[MLIR][OpenMP] Create `LoopRelatedClause` (#99506)

This patch introduces a new OpenMP clause definition not defined by the spec.

Its main purpose is to define the `loop_inclusive` (previously "inclusive",
renamed according to the parent of this PR in the stack) argument of
`omp.loop_nest` in such a way that a followup implementation of a tablegen
backend to automatically generate clause and operation operand structures
directly from `OpenMP_Op` and `OpenMP_Clause` definitions can properly generate
the `LoopNestOperands` structure.

`collapse` clause arguments are also moved into this new definition, as they
represent information on the loop nests being collapsed rather than the
`collapse` clause itself.
