Remove the need to include SkTypes.h in SkVx.h,
making SkVx entirely independent of Skia.
As an experiment, switch to checking Clang/GCC-style __SSE__ /
__ARM_NEON defines directly instead of the slightly more abstract
SK_CPU_SSE_LEVEL / SK_ARM_HAS_NEON.
Those SK_ defines only exist to help SSE detection on MSVC, which SkVx
generates serial code for anyway.
If this sticks I may do this same sort of change all through Skia.
