Alice Ryhl 48b7f4d29a rust: time: Add Ktime ...

Introduce a wrapper around `ktime_t` with a few different useful methods.

Rust Binder will use these bindings to compute how many milliseconds a
transaction has been active for when dumping the current state of the
Binder driver. This replicates the logic in C Binder [1].

For a usage example in Rust Binder, see [2].

ktime_get() cannot be safely called in NMI context. This requirement is not
checked by these abstractions, but it is intended that klint [3] or a
similar tool will be used to check it in the future.
