This reverts commit af312c9d40.
Reason for revert: improved performance, updated empty point cap behavior
to make chrome happy.
Because of the performance regression in the original CL, this is a bit
more to it than just updating cap behavior. Summary of changes for perf:
1. In asPath(), only call reset() if the type isn't a path or arc.
Otherwise it was just a wasted realloc of an empty path ref.
2. Rewrote the GrShape::simplify() to not progress through every shape
type in order, it just jumps to the appropriate type.
3. Have simplify() return whether or not the shape started out closed,
so we don't have to call GrShape::closed(), which is costly when the
shape is a path.
4. Expose the GrShape's type enum so GrStyledShape's key writing can use
switches instead of a giant block of ifs (where path happened to be
last)
The regressions showed up most heavily on desk_mapsvg and desk_chalkboard
SKPs on the Android skpbench marks. On my system, I was able to
reproduce a similar %-regression from ToT and the original CL on the
chalkboard (but not mapsvg).
Master ranged between 5.1 and 5.3ms, original CL ranged from 5.6-5.8
and after the changes listed above, I got it down to 5.3-5.5. It's not
ideal but I haven't been able to figure out anything more substantial
that it could be. At this point it may just be code layout and/or the
fact that it's now split into two types.

The geometry union part of GrStyledShape is now held in GrShape. For the
most part, GrShape is entirely style agnostic and focuses on storing
the various types of geometry, and destructing them gracefully. It also
provides a public API that unifies functionality across all shape types,
such as contains() and bounds().
GrStyledShape now just owns a GrShape and a GrStyle, and handles the
additional simplification logic that relies on knowing the effects of
the style on the draw. This is where GrShape makes some allowances for
style. Its simplify() function accepts flags that enable/disable various
simplification optimizations. Currently these are designed around
what is needed to respect path effects and stroking behaviors in
GrStyledShape. The main other user of GrShape (the new clip stack) will
always provide all flags since it treats every shape as if it were
simply filled.
Several other related refactorings were taken at the same time:
1. The implementations for asNestedRects, asRRect, etc. were moved out
of the header and into the cpp file for GrStyledShape.
2. GrRenderTargetContext relies on GrStyledShape for its stroke rect
fallbacks.
3. GrShape can hold points, lines, and rects explicitly. This let me
simplify the stroke reasoning.
