This exists due to historical limitations which have long gone obsolete.
This persists longer due to hostorical perf issues that have recently
gone obsolete on the platforms shipping Venus. Meanwhile, clients like
skiavk and ANGLE nowadays do a better job managing suballocations. The
tiny perf win from having this giant internal pool has been beaten by
the memory waste, longer one-shot jank due to largier alloc, allocations
no need to be mapped but only because host-visible is advertised across
mem types and varies workarounds and markups needed to make alignment
work and make VVL happy. Dropping it also reduces the maintenance cost.

Meanwhile, we merge the export and non-external allocate paths since
export alloc will be rejected by vn_device_memory_should_suballocate.

Add a new perf option NO_ASYNC_MEM_ALLOC. Track the ring seqno of the
memory alloc command, and do async ring wait to ensure:
- memory allocation is before resource creation
- memory import is before resource destroy

bo allocations for the below cases are after device memory allocation:
1. direct non-external mappable memory allocation
2. pool grow
3. exportable memory allocation
For (1) and (2), the bo is for mapping, which is a pure kernel operation
to happen later. So roundtrip waiting can be deferred until free memory.
For (3), the bo is for either fd export or mapping, which are both pure
kernel operations. So roundtrip waiting can also be deferred until free
memory.

For blob_mem allocated from virtgpu_virgl backend, the guest mappable
size queried can be smaller than the size returned from image memory
requirement query from the host side. Here we temporarily workaround
until we switch to use cross-domain backend in minigbm.

This patch wraps up fd import logic, which will be used later by ahb
import. This patch also removes a redundant check in need_bo.
