The `__init` method is not designed to be a public API (existence of "__"
is a hint for this); replace users with `pin_init::raw_[try_]init` which
does the same thing.

There are a few users of `__init` which are replaced as well.

Moving a GpuVaAlloc or GpuVmBo between threads currently forces drivers
to write their own unsafe Send and Sync impls. Provide the markers in
the abstraction instead.

GpuVaAlloc wraps only uninitialised memory and exposes none of it.
GpuVmBo hands out the driver data and GEM object by shared reference and
drops them in its deferred put; the DriverGpuVm trait already guarantees
both are Send + Sync, so both impls are unconditional.

DriverGpuVm permitted !Send/!Sync associated data on an abstraction whose
handles are shared and dropped across threads: obtain() runs from many
threads and the VA API performs deferred cross-thread drops. That is
unsound.

Require Send + Sync on the trait and its associated data so the GpuVm and
UniqueRefGpuVm handle impls need no per-impl bounds.

If a DriverGpuVm implementation is lifetime-parameterized, its
SmContext<'ctx> type may depend on lifetimes carried by that driver
implementation. In this case, SmContext<'ctx> is only valid if the
driver implementation outlives 'ctx.

Add a Self: 'ctx bound to DriverGpuVm::SmContext<'ctx> to express that
requirement. Then propagate the corresponding T: 'ctx bound to the GPUVM
state machine helper types that store T::SmContext<'ctx>.

This allows drivers to provide lifetime-parameterized implementations of
DriverGpuVm.

Since the introduction of DeviceContext, there is no longer a single
driver object type to equate with the GPUVM object type.

Instead of threading DeviceContext through GPUVM, remove the strict
identity between DriverGpuVm::Object and drm::Driver::Object and
instead tighten the requirement that the DriverGpuVm::Object be an
allocatable GEM object associated with the same DRM driver.

Also, make GpuVm::new() generic over DeviceContext so it can accept a
drm::Device<T::Driver, Ctx>.

Since Rust uses GPUVM via the kernel crate, which is built-in, the GPUVM
module must also be built-in to use GPUVM from Rust. Adjust the Kconfig
settings accordingly.

operations need extra data in the context since they involve a vm_bo
