Simplify InputMethodBridgeUnitTest

Simplify InputMethodBridgeUnitTest

This is a refactoring CL as a preparation to fix focus handling on
Win-Aura environment. This CL does not change any behavior of
production binaries.

Currently InputMethodBridgeUnitTest internally defines a custom
dummy class of ui::InputMethod. However this is not necessary
because we already have ui::FakeInputMethod.

This CL replaces the custom dummy class with
ui::FakeInputMethod by using DummyInputMethodDelegate.
We can reuse ui::DummyInputMethodDelegate later in other
unit tests.
