[GPUP] Improve worker thread assertions in RemoteRenderingBackend
https://bugs.webkit.org/show_bug.cgi?id=312510
rdar://174950627

Reviewed by Vitor Roriz.

Replace ASSERT(!RunLoop::isMain()) with assertIsCurrent(workQueue()) in
RemoteRenderingBackend cache methods and releaseMemory, matching the
stricter assertion already used in the filter caching path since 309995@main

(WebKit::RemoteRenderingBackend::cacheNativeImage):
(WebKit::RemoteRenderingBackend::cacheFont):
