[typedarray] Change TypedArray.p.sort implementation.
This CL uses the new function pointers and generic features of Torque to improve the performance of TypedArray.p.sort. Instead of one Load/Store builtin that dispatches at runtime based on the element kind, there are now many small builtins (one for each element kind). The sorting algorithm then uses function pointers to those small builtins, which get set once.
