feat(minifier): drop 0 from new Int8Array(0) and other TypedArrays (

#8431)

Compresses `new Int8Array(0)` into `new Int8Array()`. (then will be compress into `new Int8Array`).

Partial quote from the [spec](https://tc39.es/ecma262/multipage/indexed-collections.html#sec-typedarray):

> 5. If numberOfArgs = 0, then
>   a. Return ? AllocateTypedArray(constructorName, NewTarget, proto, 0).
> 6. Else,
>   c. Else,
>       ii. Let elementLength be ? ToIndex(firstArgument).
>      iii. Return ? AllocateTypedArray(constructorName, NewTarget, proto, elementLength).
