[GIT PULL] Rust timekeeping for v7.1

[Andreas Hindborg]

Hi Miguel,

Pleas pull these changes for rust timekeeping.

This PR expands the example section of `HrTimer`, adds a constructor for
`Delta` and marks `ClockSource` as unsafe to ensure only valid values
are returned by `ClockSource::ktime_get`.

The following changes since commit c369299895a591d96745d6492d4888259b004a9e:

Merged into `rust-next` -- thanks!

As discussed offline, this counts as a back merge, so let's avoid it
in the future unless justified. For this time around, I provided this
context in the merge commit:

    This is a back merge since the pull request has a newer base -- we will
    avoid that in the future.

    And, given it is a back merge, it happens to resolve the "subtle" conflict
    around '--remap-path-{prefix,scope}' that I discussed in linux-next [1],
    plus a few other common conflicts. The result matches what we did for
    next-20260407.

    The actual diffstat (i.e. using a temporary merge of upstream first) is:
