[move-ide] Added smart auto-completion for colon-colon (#18778)

## Description 

Currently, this PR implements most of functionality for `::`
auto-completion when the cursor is on one of the identifiers in the name
access chains.

There are some missing parts here, arguably better split to separate
PRs:
- handling of access chains in attributes
- handling of access chainss in `use` statements


Also, this PR actually removes `:` completion (auto-completion start
when typing the first character after `:`) which is consistent with what
rust-analyzer does. While we can implement auto-completion right after
`:`, the question is whether we should

## Test plan 

All new and old tests must pass
