typings: add missing typings for TypedArray

[jazelly]

Add missing typings for the TypedArray domain we used in the codebase.

This enables typing intellisense for typed array. e.g.

const buffer = Buffer.allocUnsafe(length); // FastBuffer extends Uint8Array
TypedArrayPrototypeFill(buffer, 0, pos, length);

will be evaluated to

const TypedArrayPrototypeFill: <FastBuffer>(self: FastBuffer, value: number, start?: number, end?: number) => FastBuffer
