Boris Brezillon 5f7410aa26 rust: drm: gpuvm: add SmContext lifetime bound ...

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.
