Fix bug #5175022 Easy mode in MeasuredText.setPara() is no more used
- use the real TextDirectionHeuristics constants
- make more formal that LayoutDirection should be resolved BEFORE TextDirection
- reset TextDirection if LayoutDirection is recomputed
- remove non used TextDirectionHeuristic.isRtl(CharSequence...)

Refactor Styled utility functions into reusable objects.
This takes utility functions from Styled and a few other classes and
incorporates them into two new utility classes, TextLine and
MeasuredText. The main point of this is to support shaping by skia,
to experiment with how this will look, this also introduces
character-based Arabic shaping.
MeasuredText is used by code that determines line breaks by generating
and examining character widths in logical order. Factoring the code
in this way makes it usable by the ellipsize functions in TextUtils as
well as by StaticLayout. This class takes over the caching of widths
and chars arrays that was previously performed by StyledText. A small
number of MeasuredText objects are themselves cached by the class and
accesed using static obtain and recycle methods. Generally only these
few cached instances are ever created.
TextLine is used by code that draws or measures text on a line. This
unifies the line measuring and rendering code, and pushes assumptions
about how rtl text is treated closer to the points where skia code is
invoked. TextLine implements the functions that were previously
provided by Styled, working on member arrays rather than
explicitly-passed arguments. It implements the same kind of static
cache as MeasuredText.
TextLine and MeasureText simulate arabic glyph generation and shaping
by using ArabicShaping, ported with very minor changes from ICU4J's
ArabicShaping. This class generates shaped Arabic glyphs and Lam-Alef
ligatures using Unicode presentation forms. ArabicShaping is not
intended to be permanent, but to be replaced by real shaping from the
skia layer. It is introduced in order to emulate the behavior of real
shaping so that higher level code dealing with rendering shaped text
and cursor movement over ligatures can be developed and tested; it
also provides basic-level support for Arabic.
Since cursor movement depends on conjuncts whose formation is
font-dependent, cursor movement code that was formerly in Layout and
StaticLayout was moved into TextLine so that it can work on the shaped
text.
Other than these changes, the other major change is a rework of the
ellipsize utility functions to combine multiple branches into fewer
branches with additional state.

Don't use BoringLayout to display text that has paragraph-style markup.
BoringLayout assumes it doesn't have to do any work to calculate the
line height. In this case, though, there may actually be work to be
done, so have it fall back to StaticLayout to do the more thorough job.
