We have unit tests that require api 26 to run, but we have no vulkan
bots that would run them. API 26 is supported on all O devices and I
don't think we'll ever want to run Vulkan on previous android devices.
So I think it is fine for us to just test at api 26 for all our test
bots.

This reverts commit eaecd17d7a.
Reason for revert: works fine in practice, but with a debugger attached, the MTL built-in debug pipeline assertions trigger and report size issues e.g.:
Vertex Function(vertexMain): argument _anonInterface0[0] from buffer(0) with offset(0) and length(72) has space for 72 bytes, but argument has a length(80).
Fragment Function(fragmentMain): argument _anonInterface0[0] from buffer(0) with offset(0) and length(72) has space for 72 bytes, but argument has a length(80).

This does not yet support gzip'ed svgDoc. DirectWrite just hands back
the raw svgDoc data here which may be in any format. It does not attempt
to check for the gzip header or flate the contents. Skia will eventually
need to do this itself for full support. At the moment glyphs which are
backed by a gzip'ed svgDoc will fall back to outlines.

Previously, we would treat double values outside [-FLT_MAX, FLT_MAX]
as finite. In practice, this introduces many hazards; any place in the
code which handled the double value as a float would silently convert
the value to infinity. This includes high-traffic calls like
Literal::MakeFloat.
Note that the if checks are structured in a slightly awkward way to
ensure that NaNs are treated as non-finite.

Since Metal is C++ based, it does have *some* struct padding, based on
the basic type in the structure with the highest bit-width. Rather
than track this amount, we just assume that it is 8 and round up
Metal uniform blocks to the nearest 8-byte size. This will ~never be

It was easy to construct a buffer that indicated enormous amounts of
memory had to be allocated. An easy guard is to bail out if the buffer
can't possibly fill those buffers.
Simplify the code a bit: Four years ago (well past the earliest
supported SKP version), we stopped writing out triangle fan data (by
converting to tri-lists at construction time). Remove the
deserialization support, which makes the code easier to follow.

FreeType reports that the type of a font is TrueType when the font is
logically TrueType. However, the underlying data may not be TrueType and
may be encoded in woff or woff2. The raw woff or woff2 data should not
be embedded in the PDF. If the tables are accessed individually it is
possible to subset them into a TrueType font. However, the subsetters
are not currently capable of handling a font as tables so fall back to
Type3 for now.

SkTypes.h was found exporting <stddef.h> and <stdint.h>.
Thus if a Skia file includes SkTypes.h, it did not need
to include either of those files to use things like
size_t or uint8_t respectively. [1]
This also resulted in strange IWYU warnings like:
warning: size_t is defined in "include/core/SkTypes.h", which isn't directly #included.
Thus, this CL removes those additional exports, and as a result,
adds many more includes of <cstddef> and <cstdint>.
The second change this CL is to not use the default IWYU
mappings which are hard-coded into IWYU [2]. These defaults
are valid, but make suggestions for the C version of
headers and not the C++ ones (i.e. <stddef.h> over <cstddef>).
To make these recommendations align better with our preferred
style (the C++ ones), we use IWYU with --no_default_mappings
and then have to expand our existing mappings to better deal
with how IWYU would resolve some of these headers.

The fuzzer managed to create a NaN using a carefully-crafted mix of
intrinsics and constant folding. (`cosh(421)` is a very large double,
which becomes +Inf when cast to float, which is then multiplied by 0;
zero times infinity is NaN.)
Our code which checked to see if a value is in range of an int did not
consider NaNs and their always-false behavior, so it incorrectly
decided that NaN was in range. This CL reverses the check so that a NaN
will not pass, but all other values will behave the same.
Followup CLs should probably also tighten up the folding/optimizer
behavior so that NaNs/Infs are not created at all.

The UniformManager would previously assert if it detected an alignment
error, but did not actually have any mechanism for automatically adding
padding between misaligned elements. If a user specifies a uniform
layout like `uniform float a; uniform float4 b;`, we now insert padding
between `a` and `b` so that `b` will be properly aligned. (This reuses
the logic that was originally used to trigger the alignment assertion.)
This CL fixes the bug and adds a test. The test is only active for
elements of matching size; mixed half- and full-precision elements
will need improved test logic.

The Stride() function in the UniformManager, when given a matrix type,
was intended to return the stride of a single matrix column. However, it
accidentally called `Stride(1)` instead of `Stride(kNonArray)`, which
meant that it was returning the stride for a `vec2[1]` (four floats)
instead of the stride of a `vec2` (two floats). Interestingly, this
still returned the correct answer for mat3 and mat4, because `vec3`,
`vec4`, `vec3[1]` and `vec4[1]` all have the same stride--four floats.
This CL fixes the bug and adds a test.
