Bug 1869041 [wpt PR 43577] - Revert "Prefetch: Allow use of HTTP cache for same-site prefetches", a=testonly

Automatic update from web-platform-tests
Revert "Prefetch: Allow use of HTTP cache for same-site prefetches"

This reverts commit b54f90853104c8275286bf256fe1849236b5c459.

Reason for revert: prefetch-uses-cache.sub web_tests failures, eg:
https://ci.chromium.org/ui/p/chromium/builders/ci/Linux%20Tests/b8762255064072594513/overview

Original change's description:
> Prefetch: Allow use of HTTP cache for same-site prefetches
>
> Adds functionality behind a feature flag that's enabled-by-default. In
> addition to adding WPT and some browser test coverage, it also makes
> most resources in external/wpt/speculation-rules/prefetch/resources
> non-cacheable to prevent them from interfering with tests (in
> particular we rely on request headers being injected by the wpt
> server, which doesn't happen when a cached response is used).
