Auto merge of #27417 - jdm:clear-reload, r=Manishearth

Make reload button clear the network cache.

The developer workflow in FxR is frustrating right now because of bugs like https://github.com/servo/servo/issues/24385. To allow us to put out a new release soon that addresses this papercut, these changes make the reload button clear the network cache in FxR.

---
- [x] `./mach build -d` does not report any errors
- [x] `./mach test-tidy` does not report any errors
- [x] These changes fix (kind of) #26411.
- [x] These changes do not require tests because can't test FxR.
