Amend ink! analyzer (phase 2)

[davidsemakula]

Project Abstract

This is an amendment to the ink! Analyzer (phase 2) grant.

Context:
While working on semantic analyzer updates, I noticed that I missed the chain extension associated ErrorCode type in the scoping, which (together with the impl Environment type used by env and environment ink! attribute arguments) is one the "special" types for ink!. So I'm updating the scope to include semantic analysis related to the ErrorCode type.

Updates:

• I've added a new milestone for the semantic analyzer (now milestone 4) for the chain extension associated ErrorCode type related diagnostics and quickfixes.
• I've split the language server milestone (previously milestone 4), into 2 new milestones (now milestone 5 and 6), with the second language server milestone (now milestone 6) including updates for the new ErrorCode type milestone and a relatively small bump in cost compared to the original combined language server milestone (previously milestone 4).
