Jay Cornwall 22ffe11f5c Implement SDMA path for Gfx9 ...

Gfx9 requires monotonic write pointer and doorbell.
Cound fields are 1-based compared with 0-based pre-Gfx9.

- Restructure implementation to use monotonic ring indices
- Remove redundant submission size checks (handled by AcquireWriteAddress)
- Unify copy/fill per-command limit (documentation is unclear)
