Support generic Uint8Array<ArrayBuffer>

[rbuckton]

This updates the DOM to use Uint8Array<ArrayBuffer> in some cases where the specification expects it. This addresses an error reported in microsoft/TypeScript#61432 for ajayyy/SponsorBlock.

This now also fixes AllowSharedBufferSource, which fails to include SharedArrayBuffer.

Fixes microsoft/TypeScript#61480

This should use ArrayBuffer by default than just overriding some cases, and use SAB+AB when [AllowShared] is used.

@sandersn: The implementation changed significantly. Can you take another look?

This adds 5.6, but is it worth? Can it be folded into 5.7? Err, never mind, there's no 5.7 now.

There are still package.json entries for <=5.5 and <=5.6. The <=5.5 entry handles usage in tsc prior to 5.6, which introduced IteratorObject. The <=5.6 entry handles usage in tsc prior to 5.7, which introduced generic typed arrays. The default types used will be for 5.7 and later.

Unfortunately, 5.6 cannot be folded into 5.7+ as use of Uint8Array<T> would fail in 5.6.

Makes sense to me. One question about the change to WritableStream in overridingtypes.json to make sure I understood it correctly.

[sandersn]

The output doesn't change that I could tell, so I guess this is an update to use the new subtype property for consistency?

[saschanaz]

Refraining from overrideType is a good change 👍🏻 (use of overrideType disables type dependency tracking)

(Though I would have preferred if this kind of change is file as a separate PR, as mixing it makes harder to understand it)

Still would like to change gitattributes to use only LF, looks good otherwise!
