fix: allow ast when macro errors (#4005)

# Description

## Problem\*

Resolves <!-- Link to GitHub Issue -->

LSP panics when compiling Contracts with macro #4004

## Summary\*

While processing macro, we want to populate definitions instead of
returning early in case of error encountered by macro.

## Additional Context

LSP was crashing because definitions for crate were not populated when
macro error was encountered. Normally, we collect definitions and errors
are returned if encountered.

When macro is used, macro processor was returning early from collection
process and not allowing for definitions to be populated, therefore when
other parts were attempting to access collected defs , they were not
present where expected.

This PR fixes the problem by not returning early in collection process
when macro error is encountered and allowing definitions to be collected
therefore we populate crate definitions while retaining errors
encountered on the way.
