NOTIFICATION_THEME_CHANGED"
This reverts commit 4b817a565cab8af648c88cfc7ab6481e86ee3625.
Fixes #64988.
Fixes #64997.
This caused several regressions (#64988, #64997,
https://github.com/godotengine/godot/issues/64997#issuecomment-1229970605)
which point at a flaw in the current logic:
- `Control::NOTIFICATION_ENTER_TREE` triggers a *deferred* notification with
`NOTIFCATION_THEME_CHANGED` as introduced in #62845.
- Some classes use their `THEME_CHANGED` to cache theme items in
member variables (e.g. `style_normal`, etc.), and use those member
variables in `ENTER_TREE`, `READY`, `DRAW`, etc. Since the `THEME_CHANGE`
notification is now deferred, they end up accessing invalid state and this
can lead to not applying theme properly (e.g. for EditorHelp) or crashing
(e.g. for EditorLog or CodeEdit).
So we need to go back to the drawing board and see if `THEME_CHANGED` can be
called earlier so that the previous logic still works?
Or can we refactor all engine code to make sure that:
- `ENTER_TREE` and similar do not depend on theme properties cached in member
variables.
- Or `THEME_CHANGE` does trigger a general UI update to make sure that any
bad theme handling in `ENTER_TREE` and co. gets fixed when `THEME_CHANGE`
does arrive for the first time. But that means having a temporary invalid
(and possibly still crashing) state, and doing some computations twice
which might be heavy (e.g. `EditorHelp::_update_doc()`).

Rename `hint_tooltip` to `tooltip_text` & setter getter
|
|
|
|
`hint_tooltip` -> `tooltip_text`
`set_tooltip` -> `set_tooltip_text`
`_get_tooltip` -> `get_tooltip_text`
Updates documentation, too.

Remove the optional argument p_binds from `Object::connect` since it was deprecated by Callable.bind().
Changed all uses of it to Callable.bind()

Adds `header_guards.sh` bash script, used in CI to validate future
changes. Can be run locally to fix invalid header guards.

- Use the "odd" style for TabContainers that are on a background with the same color as the default TabContainer background color to add contrast

This prevents the pitfall of UB when checking if they have been
assigned something valid by comparing to nullptr.
