Add WASM memory.copy and memory.fill docs

[felipeochoa]

Description

Add documentation for the memory.copy and memory.fill instructions to the WASM reference

Motivation

These were added by the bulk memory operations proposal. They are already in the spec:

The memory.fill instruction sets all values in a region to a given byte. The memory.copy instruction copies data from a source memory region to a possibly overlapping destination region.

Additional details

There was also a memory.fill instruction added, but I don't understand it well enough to document.

We might want to ask @eqrion for a review.

As for the docs, what is the browser support for these? We don’t usually document proposals or even spec additions before they ship into browsers.
