[skottie] SkTArray begone
SkTArray is not a good choice for tigh allocations:
- its minimum allocation count is 8
- reserve(sz) doesn't adjust capacity to the exact value, but padds
the same way as normal growth (max(sz, 8, 50%))
- no shrink_to_fit() function to trim unneeded capacity
Since keyframed properties with a small number of frames are quite
common in Lottie, this adds significant heap overhead.
Switch to std::vector(), reserve() to the estimated frame count and
shrink_to_fit() when done parsing.
