Revert of Add virtual tests for XHR with mojo-loading

Revert of Add virtual tests for XHR with mojo-loading (patchset #9 id:160001 of https://codereview.chromium.org/2463753002/ )

Reason for revert:
The new tests fail when OOPIFs (out of process iframes / aka remote frames) are possible and turn the Site Isolation Win bot red.  Most likely failure modes differ between --site-per-process mode and the expectations landed in this CL in third_party/WebKit/LayoutTests/TestExpectations (so maybe the experimental feature needs to also maintain a separate set of test expectations in third_party/WebKit/LayoutTests/FlagExpectations/site-per-process).

Example red build: https://build.chromium.org/p/chromium.fyi/builders/Site%20Isolation%20Win/builds/16899
