Auto merge of #27562 - jdm:devtools-session-history, r=paulrouget

Notify devtools of session history traversals

This makes the remote devtools and devtools panel in FxR clear the console when going backwards and forwards through session history.

- [x] `./mach build -d` does not report any errors
- [x] `./mach test-tidy` does not report any errors
- [x] These changes fix #27525
- [x] These changes do not require tests because no devtools tests.
