Konrad Sztyber 1be4e82d15 bdev: allow bdevs to report accel_sequnce support 
Modules can now report that they support accel chaining for specific
operations through the accel_sequnce_supported() callback.

The support is reported per IO type.  This allows modules to support
accel sequences for some operations, while relying on the bdev layer to
handle them for other IO types.

Only bdevs without separate metadata buffers are allowed to support this
new mode.  That's because metadata in separate buffer is expected to use
the same memory domain as data buffers.  With an accel sequence, those
data memory domains can change, while metadata's memory domain always
stays the same.  To support bdevs with separate metadata buffers, we'd
need to add separate pointers for metadata's memory domain.  For now,
simply disallow registering bdevs with separate metadata supporting
accel sequences.
