[LTL] Make ltl.delay clocking explicit (add %clock and <edge> operands)

[Clo91eaf]

Implement from #9026 to fix the implicit clock in ltl.delay

Description:

• Change ltl.delay signature to: ltl.delay %clock, <edge>, %input, <delay>[, <length>].
• Update TableGen patterns, canonicalization, lowering, tests, and docs to the new operand order.
• Folding/merge rules now require same clock+edge to combine delays.

Migration notes:

• Call sites that create ltl.delay must supply an i1 clock Value and a ClockEdgeAttr (e.g., posedge). Lowering may synthesize a clock (e.g., hw.constant) when none is available.
• Tests that assumed strict adjacency around ltl.delay may need to either:
  • accept an inserted clock op (use CHECK instead of CHECK-NEXT), or
  • explicitly assert the inserted clock op and keep CHECK-NEXT for ltl.delay.

Testing:

• Regenerated TableGen rewriters and rebuilt.
• Updated MLIR tests and FileCheck expectations to be robust against inserted clock constants.

sorry, i missing delete my repo for some git issue ... 😿
i will create a new pr soon ...

i was trapped for the ci report and try hard to reproduce the errors in my machine, i'm sorry
