Update input policy to handle embedded windows

ANR - If embedded windows are slow in handling inputs the system should blame the embedded app.

PointerDownOutsideFocus - if a user taps outside the currently focused window onto an
embedded window, treat it as if the host window was tapped.

Rename blessInputSurface -> grantInputChannel and add a name to embedded windows.
