Replace IsResizableArrayBuffer with IsFixedLengthArrayBuffer

As part of tc39/ecma262#3116, the IsResizableArrayBuffer abstract operation was negated and replaced with IsFixedLengthArrayBuffer. Update Web IDL to use the new standardized, referencing the main JavaScript specification instead of the proposal.

Fixes #1520.
