Summary:
Support rounded clipping in Nodes. Before, if a view had
a radius and had overflow of hidden, its children could still draw
outside of it (specifically, in the area between the rounded rect
and square rect) - this is due to the fact that clipping is, by
default, rectangular. This patch supports this type of rounded
clipping.

Summary:
Currently we have race conditions in DrawView related to isViewGroupClipped, where we create a copy of the DrawView before we update the clipping state, and think the view is unclipped in the next iteration.
Also we are sometimes creating a DrawView with a reactTag of 0.
This fixes both, and is part of the upcoming DrawView bounds change, but is a separate issue that is live in current source.

Our current behaviour of add then immediately remove if a view is clipped pretty much guarantees that we kill network requests for images in feed. We have a better fix for that in the pipeline, but this is a low risk fix in the meantime.

This PR was split from a commit originally in #8619. /cc dmmiller
When an inline image was larger than the specified line height,
the image would be clipped. This changes the behavior so
that the line height is changed to make room for the inline
image. This is consistent with the behavior of RN for iOS.
Here's how the change works.
ReactTextView now receives its line height from the layout thread
rather than directly from JavaScript.
The reason is that the layout thread may pick a different line height.
In the case that the tallest inline image is larger than the line
height supplied by JavaScript, we want to use that image's height as
the line height rather than the supplied line height.
Also fixed a bug where the image, which is supposed to be baseline
aligned, would be positioned at the wrong y location. To fix this,
we use `y` (the baseline) in the `draw` method rather than trying
to calculate the baseline from `bottom`. For more information

Summary: This is the most straightforward fix for the double detach issue. If a view is not attached, then addViewInLayout never propagates onAttach, and adding through attachViewToParent is a no op. We could hack something in to attach clipped FlatViewGroups in onClippingRect, but any other view that relies on onAttachedToWindow will have similar issues.

Summary:
Previously, to fix the issue of commands happening before the Views
were made and attached to the hierarchy, a check was added to see if a node
had not been mounted to a View, to update its hierarchy. In reality, we need
to do this irrespective, since a node could be mounted to a View, but its
children may not yet be attached, for example. Note that if there is nothing
to be done, this won't do extra work (i.e. applyUpdates recursively goes
through the tree from the node on which we did the operation to apply updates,
but if there are no updates, we stop traversing that praticular subtree).

Summary:
The results from measureInWindow were always wrong the first time it
was called. This was due to the fact that the view in question was not
actually a view yet, so the results were incorrect. This patch uses the
existing measure functionality (which can measure virtual nodes) to measure
the view, while modifying it to properly get the results relative to the
window instead of relative to the root view.

Summary:
Groups encountered a pretty major crash where, in many cases,
we would find that DrawCommands and Views were out of sync. This
turns out to be due to the fact that when we drop views from the
root view, we remove each child using removeChildAt (which ultimately
causes an invalidate and redraw). If this happens for a
FlatViewGroup, this causes issues where the Views are all removed,
but there are some DrawCommands (potentially DrawViews) that aren't
removed, hence them going out of sync.

Summary:
During the patch for fixing the order of UI operations, we apply
updates to any node receiving a ViewManager command in order to ensure that
nodes that were not yet mounted to a View and not yet attached to their parent
would be properly able to receive the event. However, if a node is already a
view, calling the update could cause unwanted things to happen (for example,
the View's bounds changing improperly), because we're only traversing that
node of the tree and down (instead of the entire tree). This fixes the issue
by only applying updates to the node if the view mount state has changed.

Summary:
Made some improvements to RCTText based on some of our learnings from components for android. This now resembles diffusion/FBS/browse/master/fbandroid/java/com/facebook/components/widget/TextSpec.java
Things that have improved:
- Calculation of text width is now faster (we noticed in components that .getWith() on the layout is all that is needed and it is much faster)
- Use text layout builder to abstract away a lot of the low level details of static / boring layouts and text measurements
- Handle MeasureMode correctly, previously AT_MOST was not supported.
- Better handling of RTL text by using TextLayoutBuilder where I made changes to support RTL text in components. Specifically RTL text measured with UNSPECIFIED or AT_MOST.
- There was an incorrect assumption being made that when measure() was not called the text had to be boring. This is incorrect, Arabic text is never boring for example. Also multiline text is not boring either and may have exact sizing.
