Bump LLVM to llvm/llvm-project@683e2bf (iree-org#22366)

Still carrying these reverts:
- llvm/llvm-project#160615 (See
iree-org#22171)
- llvm/llvm-project#163440 (See
iree-org#22354 (comment))

Fixes: 
- Remove deprecated references to `.CaseLowers`
- Added dependencies required due to new added dependency to LLVMIR
llvm/llvm-project#163881
