  [flang][mlir][OpenMP] Add linear modifier (val, ref, uval)

Add support for OpenMP linear modifiers `val`, `ref`, and `uval`
as defined in OpenMP 5.2 (5.4.6).

  Log Message:
  -----------
  Add OpenMP version guard for linear modifier

- Add OpenMP 5.2 version guard for linear modifier to make sure
we don't set val for OpenMP 4.5 and 5.0 which support explicit
linear modifier
- Update test to revert changes in version < 5.2
- Update declare simd test (add declare_simd for 6.0)
- Refactor logic in flang lowering

  Log Message:
  -----------
  Fix implicit val for OpenMP >= 52 and don't rely on static variables in processLinear

- Emit val for implicit linear clause if openmp version >= 52
- Turn `typeAttrs` and `linearModAttrs` from static to local to
avoid confusions about cleaning stale value
