Unify ephemeral storage trigger logic to use net::CookieOptions.

[goodov]

This PR generalizes ephemeral storage check to allow it to be used in 1p context. Also this PR restores navigation cookie handling in ephemeral storage mode (which is required for 1p-ES).
The idea is to fill net::CookieOptions with ephemeral storage values everywhere it's required and then use it in CookieMonster directly.

All planned changes can be seen here: #8881. This is a first part to simplify the PR review process.

Test Plan:

[bridiver]

I think we should change the name of this test because "navigation cookies" doesn't mean anything to me. This is presumably for network cookies?

[bridiver]

actually what we really need is to check network and JS for all tests now

[goodov]

extended/added tests to check network and JS cookie set.
