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.

Use std::swap instead. It does not appear that any external user
specializes SkTSwap, but some may still use it. This removes all use in
Skia so that SkTSwap can later be removed in a smaller CL. After that
the <utility> include can be removed from SkTypes.h.

We currently blow through string chars without checking for end-of-input.
Maybe we could avoid this upfront, when we locate the stop char: try to
determine if it's part of an unterminated string, fail immediately if
so. Figuring out if the tail is an unterminated string seems
intractable though (requires arbitrarily deep tail parsing).
That brings us to plan B:
* treat scope-closing tokens (} & ]) as string terminators
(we know end-of-input points to one of these for sure)
* adjust matchString() to check for end-of-input

The input is not guaranteed to contain well-formed scopes, so it's not
sufficient to check for end-of-stream only when popping the top-level
scope -- we have to check on every scope pop.

Pass an explicit input size instead of requiring a C string.

ASAN opines that a nullptr memcpy dest is undefined behavior, even when
n == 0. ASAN may be right.
This doesn't occur internally, in the parser, but can be triggered with
the DOM builder API (as do some tests currently).
We could say "don't do that", but if someone wants to build an empty
string/array/object, it's kind of awkward to force them to provide a
valid source pointer instead of simply e.g. Array(nullptr, 0).
So let's guard for this case to make ASAN happy.
