SkWriter32: throw in the SkTDArray towel.

I think it's looking more clear we don't have a clean way to use SkTDArray in
SkWriter32.  We can't give SkWriter32 meaningful control over SkTDArray's
reallocation without making moot SkTDArray's raison d'etre.

Let's just use an SkAutoTMalloc<uint8_t> instead.  It wants SkWriter32 to
control it.  Also, it's lower overhead: SkAutoTMalloc<uint8_t> is just a smart
poiter: no size or capacity stored.
