[DevUI DFM] Add API and backend to install and load the DFM.
This CL adds DevUiModuleProvider classes (Java and C++) as backend to
install and load the DevUI DFM. The C++ API must be called from the UI
thread. It consists of query helpers:
* DevUiModuleProvider::GetInstance().ModuleInstalled(),
* DevUiModuleProvider::GetInstance().ModuleLoaded(),
and asynchronous (i.e., takes callbacks) actions:
* DevUiModuleProvider::GetInstance().InstallModule(),
* DevUiModuleProvider::GetInstance().LoadModule().
The Java backend handles DFM installation, and implements standard
on-demand DFM installation flow. For simplicity, no Java UI elements
(e.g., using Toast or InfoBar) as used. Instead, an interstitial page
that calls the C++ API will be used.
Some sources of complexity, also encountered by VrModuleProvider (upon
which the code is based) are:
* Interaction between C++ and Java DevUiModuleProvider via JNI calls
and interaction between the singletons.
* Queue management for InstallModule() and LoadModule(), to handle the
corner case of multiple concurrent install / load requests.
