Bump FastMalloc thread cache max size to 1MB on iOS.
<https://webkit.org/b/134365>
The previous limit (512kB) comes from the old days of very-low-memory
devices, and we can now afford to spend another 512kB here.
Note that we already have a mechanism to purge FastMalloc caches on
system memory pressure.
Looks like a ~400ms progression on PLT.
