Drop mock module usage in favour of standard unittest.mock (#19263) (#19264)

Since Python 3.3 the mock module became part of the standard unittest
library as unittest.mock.

This MR removes the usage of that in favour of the standard library,
simplyfing the dependency tree and uniforming usage in code.
