Upstream BrowserState::GetStatePath()

Upstream BrowserState::GetStatePath()

When using multiple BrowserState (think saving and incognito), each one
has a different path to stored data on iOS. In order to avoid confusion
with chrome Profile change the name of the method returning the path of
a BrowserState to GetStatePath().
