Bug 1814902 [wpt PR 38347] - Reject getDisplayMedia calls without user activation, a=testonly

Automatic update from web-platform-tests
Reject getDisplayMedia calls without user activation

This CL makes sure getDisplayMedia() returned promise reject with
InvalidStateError when called without user activation. This is now gated
by an experimental blink feature as it was revered several times before.

Note that speculation rules tests are updated as well[1].
