WebView packages that cannot be chosen as WebView implementation should
be shown as disabled in the 'WebView Implementation' Dev Setting.
Simplify the logic in DefaultAppInfo a little bit to avoid
special-casing for the WebView Dev setting.
Also add tests to ensure we are correctly disabling WebView packages in
the Dev setting and showing their disabled-reasons.

Make the WebView Implementation Dev Setting look like the fullscreen
settings deriving from DefaultAppPickerFragment.
Point the Activity opened through Settings.ACTION_WEBVIEW_SETTINGS to
the class WebViewAppPicker which is our new implementation of the
WebView Implementation setting.
Ensure the new setting closes if it is reached from a user that isn't an
admin of the device.

Bug: 34966439
Test: Ensure WebView implementation Dev Setting looks ok (disabled
packages should have a text showing why they cannot be chosen).
Test: Start Intent with action Settings.ACTION_WEBVIEW_SETTINGS and
ensure the started Activity looks similar to the WebView Implementation
Dev Setting.
Test: Ensure picking a package that is no longer active, updates the
setting (so that package isn't visible anymore).

Now that we are changing the WebView package mechanism so that a package
can only be used as WebView implementation if that package is enabled
for all users of the device we need to tell the user why a package can't
be chosen as WebView implementation.
With this CL we do so in the 'Set WebView Implementation' Developer
Setting.
We code for the WebView implementation Developer Setting is now based on
the same code as that of the Debug App Developer Setting.
Bug: 32894154
Test: Ensure WebView Implementation setting shows correct packages.
Test: Ensure WebView Implementation setting shows correct descriptions
for why a package is not usable - including the case where packages are
disabled/uninstalled for a second user.
Test: Ensure the summary for the WebView Implmentation setting is
updated after changing WebView package.
Test: Ensure the WebView package Activity
(Settings.ACTION_WEBVIEW_SETTINGS) is similar to the Dev Setting.
Test: ensure non-admin user cannot start WV-picker activity through
'adb shell am start -n com.android.settings/.WebViewImplementation'
