gpu: nova-core: gsp: separate context and GPU lifetimes in GspBootContext

Browse source 
`Falcon` instances retain references tied to the lifetime of the bound
GPU. `GspBootContext` currently uses that same lifetime for its own
borrows of the `Falcon` instances and other references.

But these lifetimes are independent: the references captured by a
`Falcon` remain valid for the GPU lifetime, while the context only
borrows the `Falcon` for the duration of a boot or unload operation.
This distinction is hidden for shared references by covariance, but
cannot be ignored anymore if the context carries mutable references to
GPU subdevices, as will happen for the `Fsp` and the `Falcon`s.

Thus, give `GspBootContext` separate lifetimes for its subdevice borrows
and the GPU resources captured by those subdevices, and update its users
accordingly.
