Summary: Set layout outputs on CSSNode from C after layout calculation finishes instead of relying on calling jni gettings from java code. This should be much more efficient as it avoids a lot of jni overhead and also allows for calling getLayoutWidth() etc multiple times without incurring a penalty.

Summary: Many layout systems query the padding after calculation to as it is needs to be propagated to the underlying view system on the platform. However most nodes have no padding set on them so going 4-6 times through JNI layer to figure this out is a waste of time.

When a previous measurement used AtMost and the new one as an AtMost with a smaller constraint but still bigger than the previous computed size it should be OK to re-use the previously computed size.

Summary:
When using CSS-Layout in a C# UWP project in x86, by default the MSVC compiler defaults the delegate calling convention to cdecl, while .NET assumes that all delegates are declared using stdcall. This causes a problem when invoking such as this error:
```
Run-Time Check Failure #0 - The value of ESP was not properly saved across
a function call. This is usually a result of calling a function declared with one
calling convention with a function pointer declared with a different calling
convention.
```
This PR changes the calling convention in the C# code to reflect cdecl by using the `UnmanagedFunctionPointer` attribute and setting the calling convention to `CallingConvention.Cdecl`.
```csharp
[UnmanagedFunctionPointer(CallingConvention.Cdecl)]
public delegate CSSSize CSSMeasureFunc(
IntPtr context,
float width,
CSSMeasureMode widthMode,
float height,
CSSMeasureMode heightMode);
```
I have updated all calls as well to other functions. I

Summary:
Originally, we thought that skipping the measurement of views that were hidden would be a nice optimiatzion. Upon further review, we saw that according to Apple's `UIView` documentation:
> A hidden view disappears from its window and does not receive input events. It remains in its superview’s list of subviews, however, and participates in autoresizing as usual.
So, to keep parity with common iOS layout APIs, we are going to size and layout views, even if they are hidden.
