Functions like min, max, clamp, and mix cannot intermix vectors and scalars as
operands and return value. This updates SkSL to promote scalars to vectors if
need be before calling these functions.

Switching the math from using fMaskPtr.stride to using mask.fRowBytes
fixes the integer overflow here. However, if done naively it'd still do
the math wrong, as mask.fRowBytes is stored as a uint32_t, and the
32-bit overflow still happens, silently. So we explicitly promote to
size_t too.
As a follow up we should consider turning on 'integer' sanitizer, which
treats unsigned integer overflow as an error. Even though it's
technically defined, it's likely not intended.

This CL clarifies what is going on in the GrDrawOpAtlas and GrAtlasGlyphCache.
For the GrDrawOpAtlas:
At creation time all the allowed pages are created (with their backing GrTextureProxies) but they aren't instantiated.
The GrDrawOpAtlas::instantiate call is called in preFlushCB and allocates any pages known to be needed at the start of flush
GrDrawOpAtlas::addToAtlas is called at flush time and, if a new page is activated, will instantiated it at that time.
During compaction, an unused page will be deInstantiated but its Plots and backing GrTextureProxy will remain alive.
The GrAtlasGlyphCache reflects the changes to the GrDrawOpAtlas
It now carries a GrProxyProvider for when it needs to create an atlas
It passes in a GrResourceProvider* at flush time to allow instantiation.
It does not, yet, allocate that GrDrawOpAtlases it might ever require.

New format should be much simpler:
- only store public data (e.g. points, verbs, filltype)
- deserialize just uses public APIs
Refactor reading code to manage different (older) versions, to make
it clear (hopefully) what we can delete when we can abandon version
3 support.

This CL clarifies what is going on in the GrDrawOpAtlas and GrAtlasGlyphCache.
For the GrDrawOpAtlas:
At creation time all the allowed pages are created (with their backing GrTextureProxies) but they aren't instantiated.
The GrDrawOpAtlas::instantiate call is called in preFlushCB and allocates any pages known to be needed at the start of flush
GrDrawOpAtlas::addToAtlas is called at flush time and, if a new page is activated, will instantiated it at that time.
During compaction, an unused page will be deInstantiated but its Plots and backing GrTextureProxy will remain alive.
The GrAtlasGlyphCache reflects the changes to the GrDrawOpAtlas
It now carries a GrProxyProvider for when it needs to create an atlas
It passes in a GrResourceProvider* at flush time to allow instantiation.
It does not, yet, allocate that GrDrawOpAtlases it might ever require.
