DataView get/set Uint8Clamped methods

There are currently 11 kinds of Typed Array in the language.

Stage: 1

Motivation/Use Case

I'd like to dynamically dispatch to DataView methods based on the "type" of the Typed Array. This works great for all of the types except Uint8Clamped.

Problem

Only 10 of them have DataView get/set methods.

Here's a matrix representing the consistently available functionality for each of them:

Name	constructor	shared prototype	ArrayBuffers	DataView get method	DataView set method
Int8Array	✅	✅	✅	✅	✅
Uint8Array	✅	✅	✅	✅	✅
Uint8ClampedArray	✅	✅	✅	❌	❌
Int16Array	✅	✅	✅	✅	✅
Uint16Array	✅	✅	✅	✅	✅
Int32Array	✅	✅	✅	✅	✅
Uint32Array	✅	✅	✅	✅	✅
BigInt64Array	✅	✅	✅	✅	✅
BigUint64Array	✅	✅	✅	✅	✅
Float32Array	✅	✅	✅	✅	✅
Float64Array	✅	✅	✅	✅	✅

Solution

Add the get and set methods to round out Typed Array support.
