sensors: Add virtual sensor-related commands to testdriver (#41906)

Spec PR: w3c/sensors#470

The Generic Sensor spec used to have an Automation section, but it leaked
implementation-specific details and was not implemented anywhere. The
changes above have been implemented in Chromium and there are pending
patches there to convert the existing Generic Sensor web tests in WPT to the
new virtual sensor model, which entirely removes the dependency on Mojo
mocks and makes the tests more interoperable.

This PR adds the required infrastructure to manipulate virtual sensors from
testdriver. The 4 new commands correspond to the 4 WebDriver extension
commands added by the spec PR above.

This change was co-authored with JuhaVainio.

Related to #9686.
