[FEATURE] Symbol analysis

[SpontanCombust]

Read the code and extract symbol information from it. It is essential to all features that rely on static analysis.

• [x] Collecting workspace symbols
• [x] Symbol location
• [x] Being able to search through multiple symbol tables
• [x] Masking out symbols from overwritten script files
• [x] Duplicate check across dependency tree
• [x] priority based search through dependencies - search through dependencies in the correct order of how they would overwrite/overshadow each others scripts
• [x] native symbol symbol table - store therer all symbols that are accessible in code, but are not declared anywhere explicitly
• [x] handling array type symbols - when to add, remove etc.
• [x] class inheritance handling - how in the body of a child class you can expect to be able to use symbols from the base class
• [x] unqualified identifier context building
  • [x] gathering globally available symbols
  • [x] enum members being globally available
  • [x] class symbol inheritance

This has been to some degree in the analysis crate, but hasn't been used in the LSP.

Script symbol analysis has been first rolled into the Language Server in dd80446f and added a debugging editor command in 3e09621e to view symbols from a requested document.
