[UWP] Label MaxLines doesn't work (#4528)

* Update from origin (#8)

* [C] VisibilityConverter Trims input (#3581)

For CSS purposes, the VisibilityConverter was added, and actually
replaced the `Boolean.Parse(str)` call for parsing Visibility.
`Boolean.Parse()` trims input, and the converter was not, so this was a
regression.
This changes Trim() the input, to be fully backward compatible.

- fixes #3554

* Ensure ConstructorCountId and TimeId elements are available before querying them (#3588)

* For consistency with ResourceDictionary, expose the Source for a StyleSheet (#2589)

This would allow previewer/designer/reloader to determine the source of a
stylesheet and refresh its content when appropriate.

* Revert "For consistency with ResourceDictionary, expose the Source for a StyleSheet (#2589)"

* Make GetIconDrawable virtual (#3967)

By making GetIconDrawable virtual for the Android TabbedPageRenderer it allows for the icon to come from other sources (like glyph fonts). This will work for both top and bottom tabs.

* [msbuild] use portable pdb files (#4201)

Currently, on the first build of a "Hello World" Xamarin.Forms app,
you will see this in the build log:

    ConvertDebuggingFiles
        Parameters
            Files
                C:\Users\myuser\.nuget\packages\xamarin.forms\3.1.0.697729\lib\MonoAndroid10\FormsViewGroup.pdb
                C:\Users\myuser\.nuget\packages\xamarin.forms\3.1.0.697729\lib\MonoAndroid10\Xamarin.Forms.Platform.Android.pdb
        OutputItems
            _ConvertedDebuggingFiles
                C:\Users\myuser\.nuget\packages\xamarin.forms\3.1.0.697729\lib\MonoAndroid10\FormsViewGroup.dll
                C:\Users\myuser\.nuget\packages\xamarin.forms\3.1.0.697729\lib\MonoAndroid10\Xamarin.Forms.Platform.Android.dll

The logging is a little weird here, but this `ConvertDebuggingFiles`
MSBuild task takes about 100ms on my machine.

What is it doing?

The Mono debugger can support two types of debugging files:
- `mdb` files
- "portable" `pdb` files

If Xamarin.Android's build finds a "non-portable" `pdb` file, we have
to run it through this task to convert to an `mdb` file... This gives
us proper stacktraces for `FormsViewGroup.dll` and
`Xamarin.Forms.Platform.Android.dll`.

You can change the type of debugging symbols in your project with the
`DebugType` setting, which has these options:
- Blank or `None`: don't generate symbols. (Although Xamarin.Android
  has funny behavior here, see:
  https://github.com/xamarin/xamarin-android/issues/2282)
- `Full` generates an `mdb` file, this is a Windows-proprietary format
  for debug builds
- `PdbOnly` generates a "non-portable" `pdb` file, a
  Windows-proprietary format for release builds
- `Portable` generates a "portable" pdb file, which is the new
  standard that works for debug and release builds. New SDK-style
  MSBuild projects use this option by default.

These values are not case sensitive, I have mostly seen them lower
case in newer projects.

So what does Xamarin.Forms need to do?

Use `<DebugType>portable</DebugType>` in any Android class library or
app project. Other platforms, this is optional, not as much benefit. I
have heard that `DebugType=portable` might cause a problem on UWP.

* Xamarin.Forms will ship "portable" `pdbs` in its NuGet package for
  `FormsViewGroup.dll` and `Xamarin.Forms.*.Android.dll`. Developers
  won't pay the 100ms on initial build.
* Initial build times for `Xamarin.Forms.sln` will be slightly better
  for development, although I didn't measure the difference here.

* [C] VisibilityConverter Trims input (#3581)

For CSS purposes, the VisibilityConverter was added, and actually
replaced the `Boolean.Parse(str)` call for parsing Visibility.
`Boolean.Parse()` trims input, and the converter was not, so this was a
regression.
This changes Trim() the input, to be fully backward compatible.
