feat(compile): Noir std lib embedded

[kobyhallx]

Related issue(s)

Relates to #951

Description

It's beneficial to embed std lib into distributed binary:

1. Source resolution does not concern itself with differences between execution environments (eg. native vs browser)
2. Source resolution does not concern itself with differences between systems and default file locations
3. Source resolution does not concern itself with differences between systems and file permissions
4. Distribution of artifacts becomes more straightforward with less maintenance needed for installation scripts

Summary of changes

1. noir_stdlib/src contents get embedded as StdLibAssets in crates/fm/src/file_reader.rs
2. StdLibAssets is asked for source upfront during read_file_to_string routine
3. crates/nargo/src/cli/mod.rs understands that StdLibAssets are embedded with std/ prefix and adds such search path for create_non_local_crate routine.

Documentation needs

Std lib no longer needs to be present on a host file system, and libraries do not need to provide the source in alternative ways, ie. source resolution in browser

Now that we'll always have the stdlib available, should we not embed the addition of the stdlib onto the end of Driver::resolve_root_config? Ah misread Resolver as Driver, in any case we should be able to abstract away the addition of the stdlib into the dependency graph.

agreed, should be refactored to more common path at later stage

Looks good. I've run a quick test locally just to confirm that we're actually pulling the stdlib from an embedded version and all looks good.
