PR #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.
* Updates Uint8ArrayConstructor to match MDN documentation.
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array/Uint8Array
```
new Uint8Array(); // new in ES2017
new Uint8Array(length);
new Uint8Array(typedArray);
new Uint8Array(object);
new Uint8Array(buffer [, byteOffset [, length]]);
```
While the previous constructors aren't significantly different from the new, it would prevent someone from doing `new Uint8Array(myBuffer, undefined, undefined)` since there was no overload that accepted undefined as a second parameter and buffer as first.
Fixes#38446
* Fixes constructor defenition for all other typed arrays.
* Renames property to `array` since it is no longer an `arrayOrBuffer`.

* make splice `deleteCount` required in es5.d.ts
In ES5 `deleteCount` is not an optional argument. If it is not provided it defaults to 0 as a side effect of `undefined` being converted to an integer.
In ES6 `deleleteCount` is optional, and it defaults to the length of the array minus the start index.
If you are targeting ES5 but don't provide `deleteCount` the behaviour will be different depending on the environment your build is running in.
fixes#32638
* update baselines
Previously subtypes of Error extended Error, but the matching subtypes
of ErrorConstructor did not extend ErrorConstructor. The members in
es5.d.ts are identical, so there's no need except for allowing interface
merging into ErrorConstructor to affect subtypes as well.
* Add this-parameter workaround to Array.filter
Allows anys.filter(Boolean) to once again return any[], not unknown[].
* Add any constraint to Boolean factory function
I want to test how well this works.
* Remove Boolean factory type guard
* Remove typeGuardBoolean test
