Simplify path allocation, clean up resources correctly

Simplify path id allocation in NVPR backend. Instead of using
an AVL tree of path id ranges for the first 65535 ids, use just
a simple stategy of overallocation and "bump index".

Fixes the bug where previously overallocated ids were not deleted.

The advantage is that the implementation is simple and all allocations
go through overallocation, not just the first 65535 of the 1-range
allocations.

Removes the logic where paths were cleared with setting path data to
null instead of deleting the whole path. Now deleted paths are just
deleted normally. These operations should have equivalent performance on
command buffer. Deleting the path should enable the driver to do more
maintainance.

Removes the GLNameAllocator, as it was only used for paths. In order for
it to be used for other IDs, it probably would need to be re-written to
support cleanup and arbitrary ranges. Also, the interface would probably
need to be changed to not requiring the block to be allocated before it
could be managed by the structure.

Fix SkXfermodeImageFilter GPU fast path for differing sizes.

The GPU fast path was not doing the correct thing for input bitmaps of
differing sizes. This change brings the fast path in line with the
slow path: use the union of foreground and background bounds as bounds,
offset the draw context by the bounds translation, and translate the
foreground and background independently by their respective offsets.

Finally, we add a texture domain for the background fragment
processor, since we may access texels outside its domain.

Note: this adds two new test cases to the xfermodeimagefilter GM, so
those will need to be rebaselined.

Fix SkTileImageFilter when srcRect is a superset of bitmap bounds.

If the input bitmap passed to SkTileImageFilter does not fill the
srcRect, we were tiling this incorrectly (see the first sample
from tileimage filter -- it draws from a srcRect of 12,12 50x50
to a dstRect of 0,0 50x50. There should be no tiling at all
in this case!)

In order to fix this, we need to pad the bitmap out to srcRect,
and tile with that. In order to tile correctly in the GPU case,
we need to request a tileable texture.

NOTE: this will change the results of the tileimagefilter GM (correctness,
and added src / dest rects).

SkPaintFilterCanvas skip-draw support

At the time SkPaintFilterCanvas was introduced as a SkDrawFilter replacement,
no clients were relying on the draw veto logic.  Now Chromium does.

To facilitate migrating off SkDrawFilter, let's augment SkPaintFilterCanvas
with skip-draw semantics.

A side effect of the CL is that now we call the filter virtual even for null
paints.

SkSwizzler: Factor skipping zeros out into a helper function.

This skips only leading zeros per-scanline, not all zeros, but my bet is that
leading zeros are all that matters: it's got to be rare that a scanline is both
larger than 1024 pixels and has runs of 1024 transparent pixels in the middle.

We're paying quite a bit of function-call overhead per pixel.

On one test image we spend 3.5% of our total time in swizzle_rgba_to_n32_premul() and 8.8% of our total time in SkPreMultiplyARGB().  That turns into just 8.8% of our total time in swizzle_rgba_to_n32_premul() after inlining.

That's about a 30% speedup.

Clean up SkXfermode_opts.h

It seems that MSVC + __vectorcall don't play well together,
so back ourselves out into a situation where we don't need it.

   - Inline transfermode functions.  This removes the need for SK_VECTORCALL.
   - Remove 565 destination specializations.
     Blending into 565 is not speed-critical enough to merit the code bloat.
   - Removing 565 specializations means a bunch of Sk4px code is now dead.

8888 xfermodes generally speed up a bit from inlining, smoothly ranging from no change down to 0.65x for the fastest functions like Plus or Modulate.

565 xfermodes generally slow down because we're doing 565 -> 8888 and 8888->565 conversion serially[1] and using the stack, smoothly ranging from no change up to 2x slower for the fastest functions like Plus and Modulate.

Use ::std for is_empty, is_class, add_xxx_reference, remove decay.

SkTLogic.h contains implemenetations of is_empty, is_class, decay,
decay_t, add_lvalue_reference, add_rvalue_reference, and
add_rvalue_reference_t. The declaration of is_class is only used by
is_empty. The current implementation of is_empty will not work
correctly with 'final'. The current implementation of
add_lvalue_reference does not support clarifications in c++17. No Skia
code is currently using decay, decay_t, add_rvalue_reference, and
add_rvalue_reference_t. In addition, there are no known issues with
any of these in ::std with any supported compiler.

The implementations of is_function and is_convertible are commented to
note why they are still present.

  - extend ViaSerialization reference checking to ViaPicture, ViaSecondPicture,

  - suppress current reference check failures with --blacklist

I'm open to following up on changing how those suppressions work.

Passing --nocheck turns off these invariant checks, letting us debug failures with normal image diff tools.

Set up some hooks for premul/swizzzle opts.

  You can call these as SkOpts::premul_xxxa, SkOpts::swaprb_xxxa, etc.

  For now, I just backed the function pointers with some (untested) portable
  code, which may autovectorize.  We can override with optimized versions in
  Init_ssse3() (in SkOpts_ssse3.cpp), Init_neon() (SkOpts_neon.cpp), etc.

More <type_traits> for SkTLogic.h.

SkTLogic.h specifies a number of declarations now found in
<type_traits>. This removes some of these declarations from SkTLogic.h
in favor of the ::std versions. These declarations are fairly safe to
change as the implementations are striaght forward and no known stl
implementations are known to have issues with them.
