There is some relatively cheap math we can do to determine easy cases
when the inner join geometry can be skipped. This CL is not
comprehensive in that there may be other cases where we can skip the
geometry.
Only handling miter joins in this CL - the other join types can likely
have similar logic, but will require a bit more computation to compute
the inner (reflected) miter point.
Misc notes:
- Added SK_LEGACY_INNER_JOINS ifdef in the event that clients depend on
the old behavior.
- Modified stroker to track "previous previous" point, which is the
start point of the previous line segment.

Discovered this while converting the remaining gradient FPs. The idea is
explained in the comment - we want to detect when we're sampling a child
that was converted to pass-through. Rather than directly checking for
that, I was looking at the explicitly-sampled flag. This is usually
correct. However - that flag is propagated to all child FPs, independent
of sample-usage. In this situation, we would end up not clearing coords,
and passing the incorrect default (float2(0)), rather than the actual
incoming coords.

Ycbcr images in vulkan can use anywhere from 1 to 3 descriptor set slots.
This comes from some gpus needing to internally treat the different
planes as different textures/samplers. So when you allocated a desc set
that includes a ycbcr image it may actually use up 3 desc set slots from
the pool. Nothing else changes in how we use the VkImage or descriptor
set. Just a matter of accounting for it in the pool.

Particlarly with runtime FPs, this is a poor space/time tradeoff.
This doesn't completely undo the memory losses from the linked bugs.
Some of it is the unavoidable cost of initializing the runtime effect
compiler - but that's going to happen once, sooner or later. It does
reduce the heap impact of each effect from ~64k to something like 2-3k,
depending on the effect.

skif::Mapping's deviceToLayer space had a punt when the device matrix
was not invertible and just returned the value unmodified, silently.
In this instance, it meant that conversion of device bounds into layer
space produced non-empty bounds, but the actual non-invertible CTM
would always result in an empty layer.
Now skif::Mapping asserts that its device matrix is invertible and
caches that inverse. The SkCanvas's get_layer_bounds_and_mapping checks
for invertibility first.
This doesn't quite fix the linked fuzzer bug's test case, but allows
it to proceed past the saved layer with image filter.

This is a reland of 3722d3195b
Original change's description:
> Remove all instances of incorrect coverage with DMSAA
>
> Here we pivot and handle DMSAA differently depending on platform:
>
> 1) Desktop GL and EXT_multisample_compatibility: Here it's easy to use
> all our existing coverage ops because we can just call
> glDisable(GL_MULTISAMPLE). So we only trigger MSAA for paths and
> use the coverage ops for everything else with MSAA disabled.
>
> 2) EXT_multisampled_render_to_to_texture (86% adoption on Android):
> The assumption here is that MSAA is almost free. So we just allow
> MSAA to be triggered often and don't worry about it.
>
> Devices that neither support #1 nor #2 just don't get DMSAA for now.
