Make numeric Array constructors take ArrayLikeBuffer union

PR microsoft#38449 changed the second overload of the constructor for Int8,
Uint8, Int32, Uint32, Int16, Uint16, Float, Float64 -Array so that it no
longer includes `ArrayBufferLike`. It's just `ArrayLike<number>`.
This is fine except in the case that
the caller provides exactly `ArrayLike<number> | ArrayBufferLike`. This
PR adds ArrayBufferLike back so that the union is once again accepted.

This avoids a breaking change, in particular in one Microsoft-internal
codebase.
