ES2015 TypedArrays missing all methods they ought to share with regular Arrays, like map/indexOf/includes etc

[p-bakker]

All TypedArray implementations ought to have a large chunk of methods that regular Arrays also have, like indexOf/includes/map/forEach etc. However, those all seem to be missing, see https://compat-table.github.io/compat-table/es6/ > built-ins > typed arrays

In addition to the missing methods that are defined in ES2015 (ES6):

• ES2016 specified the addition of the .includes() method on (Typed)Arrays
• ES2020 specifies two new TypedArray variants, see ES2020 support BigInt64Array & BigUint64Array Typed Arrays #1410
• ES2022 specifies the .at() method on (Typed)Arrays
• ES2024 adds new methods via the Array find from last
• ES2024 adds new methods via the Change Array by copy, see Support ES2023 Change Array by copy #1307
