All of std should be fully auto-completable by tools like zls

[Jarred-Sumner]

Zig Version

0.11.0-dev.1095+8bd734d60

Steps to Reproduce and Observed Behavior

1. Type std.os.sockaddr
2. No completions appear. Data types don't either. Go-to definition doesn't help

Expected Behavior

All of std should be fully auto-completable from the text editor.

When you use Rust, completions work relatively consistently. In-editor feedback reports when the wrong number of arguments are passed to a function. It doesn't take more than a second or two to update the red squiggly lines. This improves developer productivity.

When you use Go, completions work too.

Closing as a duplicate of #615. Specific things that zls does not complete are zls bugs/limitations, likely due to zls not (yet?) implementing a complete comptime evaluation engine.

The only thing we can do on the Zig compiler side is to expose the analysis done by the compiler over some API to make things easier for zls and other completion engines.
