Update GDScript parser, fix 4 issues

This commit updates the parser, which addresses 4 parsing issues:

- In Lua-style dicts, string keys were not supported (e.g. { "key" = value }). Added support for it
- Annotated signals errored out in inner classes. E.g. @warning_ignore() signal exited
- Inline if in lambdas like func(): if condition: ... caused an error
- @tool extends Node on one line was not supported. the annotation was parsed standalone and extends errored out

This addresses these 4 tickets in the formatter:

Close GDQuest#209: Missing space between extends and class_name GDQuest#209
Close GDQuest#201: if statements inside of lambdas are broken after formatting. GDQuest#201
Close GDQuest#136: Nested dictionaries using = for key value pairs are missing a space in some cases GDQuest#136
Close GDQuest#195: nnotation in inner class fails to parse causing broken formatting GDQuest#195
