We need a way to pass flags to rombuilds in Raptor via extension flm interfaces, so that the CPP pass
of the rom input files can be informed what toolchain we are building with and conditionally
include or exclude files depending on whether the toolchain could build them.

If set to ETrue, media driver reads on this drive are considered to be asynchronous
i.e. interrupt driven. This results in read-aheads being issued before completing a client read request.
If set to EFalse, media driver reads on this drive are considered to be synchronous
i.e. issuing a read-ahead is likely to block any client thread which will normally be running at
lower priority than the media driver's thread. In this case read-aheads only happen during periods
of inactivity so as to improve latency: this is achieved by lowering the process of the drive thread
if there is only one read-ahead request in the drive thread's queue.
