Allows to opt-out from the device deduplication logic. This is not the
recommended way of using dev handles, but it's necessary for native context:
in this situation one process (eg: Qemu) will init many devices and we
want independent devices to make sure guest applications are isolated from
each other.

This is the same functionnality that amdgpu_va_range_alloc offers,
except it's now usable without a device handle.

This will allow applications to use this feature without a device.
The first use case will be native context: we want VA address to
be managed by the guest (to avoid a round-trip to the host to only
generate a VA) but the amdgpu_device only exist on the host.

Dual purpose:
- The drm fd dedupe functionality confuses the radeonsi
amdgpu winsys if radeonsi isn't the first thing opening
the device. By exposing the fd we can detect this case.
- For a common mesa Vulkan sync objects implementation
with syncobj. (notable: no buffer allocation)
Both shouldn't interferece with libdrm_amdgpu functionality
though it does somewhat piece the abstraction of the library.

In Vulkan we have extensions to assist with capture in replay in a
world where addresses are returned to the application. This involves
creating buffers at the same VA during replay as they were during
capture.
By itself libdrm_amdgpu already has support for this, but there is
the obvious failure mode that if another buffer is already allocated
at that VA things fail spectacularly. This is an actual issue as
internal buffers, like winsys images or shader binaries also
participate in the same VA allocation.
To avoid this problem applications have to create buffers which
are going to be captured with a flag, and the implementation is to
separate VA allocation for those buffers to reduce the collision risk:
"Implementations are expected to separate such buffers in the GPU address
space so normal allocations will avoid using these addresses. Apps/tools
should avoid mixing app-provided and implementation-provided addresses for
buffers created with VK_BUFFER_CREATE_DEVICE_ADDRESS_CAPTURE_REPLAY_BIT,
to avoid address space allocation conflicts."
This patch implements that by adding a flag for these buffers and allocating
address space from the top of the address range instead of the bottom.

This way we can override the priority of a single context using a
master fd.
Since we cannot usefully create an amdgpu device of a master fd
without the fd deduplication kicking in this takes a plain fd.
This can be used by e.g. radv to get high priority contexts using
a master fd from the primary node or a lease.
