[WPT/mixed-content] Tentatively rename source_scheme to source_protocol

To use common names in referrer-policy and
mixed-content tests.

The final goal is to rename all to `source_scheme` (which is done in
https://chromium-review.googlesource.com/c/chromium/src/+/1718991).
This CL renames first `source_scheme` to `source_protocol`,
just to avoid rebasing in a long chain of commits.

Generated files will be updated after some more changes, not now.
