SendFileGetsCanceledByDispose failed with ObjectDisposedException

[danmoseley]

I'm not sure whether this is specific to the test, or just random timing that could affect any test (in which case this issue could be closed as a dupe maybe).

Was running locally, with today's main, on Windows 21H2.

There is another report (coreclr windows x86 release) in one of the 7.0 backport PR's CI run on #75702 (@carlossanlop comment).
I couldn't be able to repro this unfortunately. We need to investigate it.

[karelz]

Triage: Happens very rarely -> 8.0. We should investigate.
