FrameFetchContext should respect BypassingCache for main resources

Existing code respects a parent frame's policy rather than
FrameLoadTypeReloadBypassingCache for main resources.

This isn't consistent to other sub-resources, and it can respect
BypassingCache rather than checking the parent policy because
the parent always return BypassingCache in such cases.

The parent frame can have a different policy if we have an UI
to trigger a per-frame bypassing reload. But we do not and won't today.
Even we have a per-frame bypassing reload, this change should be still
reasonable.

FrameFetchContext should respect BypassingCache

Existing logic in determineWebCachePolicy() respects request conditions
such as request being a conditional, and requesting method being POST,
even for FrameLoadTypeReloadBypassingCache.

But, BypassingCache is stronger condition for cache handling, and should
overwrite ValidatingCacheData.

FrameFetchContext should not always respect conditional requests

Existing logic respects conditional requests for sub-resources always.
But we should respect WebCachePolicy for the frame.

This old code might affect history navigation performance badly because
it validates cache entries for conditional resources on history navigation.

FrameFetchContext should handle all FrameLoadTypes

Now, determineWebCachePolicy() does not care for FrameLoadTypes
that are used in edge cases.

This patch adopts the corresponding logic for such types.
