Add better type info everywhere

[rune-scape]

its slightly common to see 'NativeType(AttachedScriptType)' in an error message
but not common enough
this kinda standardizes it to 1 method get_full_type_name and uses it in many places
+also ContainerTypeValidate::get_contained_type_name()

the exact format of the full type name is of course up for debate but what i came up with:
examples of complex type name results:
Button (CustomButton)
Button (res://ui/CustomButton.gd)
GDScript[PlayerController]
GDScript[res://common/GameData.gd]
Array[GDScript (PlayerController)]

I'm not sure about adding module dependencies to core

[rune-scape]

theres mono and regex module dependencies in core and i think its properly #ifdefd
but its also not crucial to have the fully qualified typename i supose

[AThousandShips]

theres mono and regex module dependencies in core

There absolutely are, what I meant was adding more, I'd say we might instead want to achieve this with adding functionality to core that can be implemented in modules, like adding them to Script, that way we maintain separation

[rune-scape]

that makes sense,, i feel a bit silly for not immediately agreeing with u

removed the dependancy on GDScript
but inner classes and builtin scripts may be displayed wrong, bc i think those aren't represented in Script::get_path()
maybe adding virtual Script::get_debug_name() in another PR is good idea?
