feat(Code Editor): Indentation markers, window completions, line wrapping

[ruchamahabal]

Indentation markers

Before:

After:

Window completions

Added completions for window functions - console, setTimeout, etc

Line Wrapping

Enabled line wrapping if line numbers are enabled

Other:

• fix: pressing tab anywhere indents the whole line, not just the text that follows
• exclude private object keys from window & studio completions - completions like VUE_APP were also being shown although they don't exist in the eval context
