commit 563dc4a98290952cd8058a891574bfecce24c03c

Refactoring Reload in NavigationManager and CRWWebController.

Previously, the |Reload| function in NavigationManager goes all the way
up to BrowserViewController to call web state's |openURLWithParams|,
which is completely unnecessary. Additionally, CRWWebController doesn't
use the transition type to call |-reload| when appropriate.

This CL first eliminates the excessive indirections by changing the
implementations of |Reload| function in NavigationManager to call
|LoadURLWithParams| directly and then updates callers of
CRWWebController's |Reload| to call NavigationManager's |Reload| to
correct layer violations.

This CL also adds a DCHECK to CRWWebController's |-loadWithParams:|
to make sure that it won't be called with PAGE_TRANSITION_RELOAD.
