orientation-event: Add Permissions Policy integration tests

Add tests for deviceorientationabsolute, deviceorientation and devicemotion
as described in
https://w3c.github.io/deviceorientation/#permissions-policy-integration:

• The deviceorientation event requires the "accelerometer" and "gyroscope"
  features.
• The deviceorientationabsolute event requires the "accelerometer",
  "gyroscope" and "magnetometer" features.
• The devicemotion event requires the "accelerometer" and "gyroscope"
  features.

(WebKit currently requires the "magnetometer" feature for deviceorientation
events, see https://bugs.webkit.org/show_bug.cgi?id=271891).

The tests being added follow permissions-policy/README.md's recommendations:

• Tests with different Permissions-Policy header values and how they
  influence usage in the top-level frame, same-origin iframes and
  cross-origin iframes.
• Different values for the "allow" attribute and how they influece
  same-origin and cross-origin iframes.
• Usage of the "allow" attribute with redirection.

This is the minimum amount of coverage we need. These tests can be expanded
to include:

• Calls to run_all_fp_tests_allow_self() to test the behavior of the
  default policy for each feature (it requires making the function work with
  more than one feature).
• The relative orientation to absolute orientation fallback behavior that
  depends on whether the "magnetometer" feature is enabled.
• Not enabling all features (it may cause an explosion in the number of
  tests though).
