Drops support for the WebAssembly text format (#614)

Browse Source 
This drops the text format (%.wat) and renames
InstantiateModuleFromCode to InstantiateModuleFromBinary as it is no
longer ambiguous.

We decided to stop supporting the text format as it isn't typically used
in production, yet costs a lot of work to develop. Given the resources
available and the increased work added with WebAssembly 2.0 and soon
WASI 2, we can't afford to spend the time on it.

The old parser is used only internally and will eventually be moved to
its own repository named watzero, possibly towards archival.

See #59
