[VITIS-15472] Add io_uring changes to adf_runtime_api.cpp files

[ManojTakasi]

Problem solved by the commit

Adds an optional io_uring-style async path for GMIO shim BD enqueue on edge AIE.
when enabled, BD programming uses XAie_DmaWriteBdAsync and queueing uses XAie_DmaChannelPushBdToQueueAsync, with completion handled via XAie_AsyncWaitNr, instead of the synchronous XAie_DmaWriteBd / XAie_DmaChannelPushBdToQueue sequence. This is intended to improve throughput when the AI Engine driver stack supports these async entry points.

Waiting for io_uring changes to be merged in the aie-rt repo. After that, we can merge this PR.

Bug / issue (if any) fixed, which PR introduced the bug, how it was discovered

his is a performance enhancement

How problem was solved, alternative solutions (if any) and why they were rejected

Plumb an io_uring flag through config_manager and in gmio_api::enqueueBD
async path builds the same BD fields as before, then submits with the async APIs and waits/errors consistently via a small helper around XAie_AsyncWaitNr.

Risks (if any) associated the changes in the commit

low

What has been tested and how, request additional testing if necessary

Tested on vck190 hw emulation by generating and installing the xrt package

Documentation impact (if any)

Yes. I will update the document once this PR is merged.
