Naively embedded platform views on Android were never able to receive
keyboard input, because they were never focusable. So far we've worked
around the limiation by hooking into InputMethodManager and proxying the
InputConnection from a focused window over to the embeded view.
Android Q changed InputMethodManager to be instanced per display instead
of a singleton. Because of this our proxy hook was never being called,
since it was being set up on a different instance of IMM than was being
used in the virtual display.
Update `SingleViewPresentation` to store the IMM from the focused window
and return it whenever there are any calls to `INPUT_METHOD_SERVICE`.
This hooks our proxy back into place for the embedded view in the
virtual display. This restores the functionality of our workaround from
previous versions.
Unfortunately there's still a lot of noisy error logs from IMM here. It
can tell that the IMM has a different displayId than what it's expecting
from the window.
This also updates the unit tests to support SDK=27. SDK 16 doesn't have
DisplayManager, so there were NPEs attempting to instantiate the class
under test.
The previous attempt to do this by setting the theme to
Theme_Translucent_NoTitleBar was reported to offsetting touch events on
specific Xiaomi devices.
By default alpha is not preserved for the VD's contents.
We make the window translucent as a side effect of doing so is preserving alpha.
There should not be extra performance cost for setting the window to be translucent as there is only a single window within the VD.

With this, plugins can know whether or not their input connection should
be cached. In very rare cases this can be used by plugins to know how to
more properly handle their own input connections, in cases where they're
overriding typical input behavior themselves.
The previous logic allowed proxying for any view that belonged to one of the platform views' virtual displays which may lead to us allowing proxying for a view that the platform view isn't allowing proxying for, previous logic also didn't account for unattached views.
This change instead delegates the decision to the platform view.
We use the fact that each virtual display has its unique context to associate any view with its relevant virtual display.
A nice side effect of calling the platform view's checkInputConnectionProxy for webviews is that the plugin now has a way to get a handle to the ThreadedInputConnectionProxyView, which may be useful for getting keyboard working on webview's prior to Android N.
Add views that are added directly to a platform view's window as siblings to the platform view's container view, rather than as children of a full screen container.
This prevents a false-negative for a visibility check from a specific ads SDK (Teads), which [reported the following warning](https://github.com/flutter/flutter/issues/12114#issuecomment-500906158):

#9203 broke the keyboard_resize integration test(see more details in flutter/flutter#34085 (comment)).
This re-lands @9203 and fixes the issue the integration test uncovered by always allowing to hide the keyboard.

Generally what this PR is doing is setting up a delegation mechanism
for Android's onCreateInputConnection.
It works by letting the framework know when an embedded view gets loses
focus(within the virtual display), the framework maintains a focus node
for each Android view that is kept in sync with the focus state of the
embedded view.
The TextInputPlugin is extended to allow for 2 type of text clients a
"framework client"(what we had before) and a "platform view client".
When the AndroidView's focus node in the framework is focused the
framework sets a "platform view text client" for the TextInputPlugin,
which will result in the TextInputPlugin delegating
createInputConnection to the platform view.
When a platform view is resized, we are detaching it from a virtual
display and attaching it to a new one, as a side affect a platform view
might lose an active input connection, to workaround that we "lock" the
connection when resizing(by caching it and forcing the cached copy until
the resize is done).
Additional things worth calling out in this PR:
To properly answer which views are allowed for input connection
proxying we compare a candidate view's root view to the set of root
views of all virtual displays.
We also preserve a view's focus state across resizes.
Note that this PR only wires text for the io.flutter.view.FlutterView
For the new Android embedding some additional plumbing is necessary.

In breaking change flutter/engine#4487, a typo was fixed in our Android
APIs correcting RequestPermissionResult to RequestPermissionsResult
(note the 's' on Permissions) for consistency with the Android SDK.
Various tombstone comments were left to help guide developers in the
right direction. These comments were slated for removal in March of
2018; at over a year later, we can probably safely remove them.
Corects a bnuch of typeos throughout teh engien codebsae. Also makes
a couple minor Commonwealth -> US spelling adjustments for consistency
with the rest of Flutter's codebase.

Delegate a11y events and action to/from embedded Android platfrom views.
This handles delegation of:
* AccessibilityNodeProvider#performAction
* ViewGroup#requestSendAccessibilityEvent
* View#onHoverEvent
Additionally updates the currently input accessibility focused node state that is
tracked by the a11y bridge when an embedded view's node is focused.
