Issue description

I actually fixing all the warnings that popup in my plugin after remove the default exclude script checks for the addons folder.

Using ResourceSaver.save says:
The flags bitmask can be specified to customize the save behavior using SaverFlags flags.

But let the compiler do report incorrect warnings
using the flags as bitmask (ResourceSaver.FLAG_BUNDLE_RESOURCES|ResourceSaver.FLAG_REPLACE_SUBRESOURCE_PATHS) is popup warnings.

[Ignorieren]Zeile 10 (INT_AS_ENUM_WITHOUT_CAST):Integer used when an enum value is expected. If this is intended cast the integer to the enum type.
[Ignorieren]Zeile 10 (INT_AS_ENUM_WITHOUT_MATCH):Cannot pass 66 as Enum "ResourceSaver.SaverFlags": no enum member has matching value.

Steps to reproduce

ResourceSaver.save(GDScript.new(), "res://test.gd", ResourceSaver.FLAG_BUNDLE_RESOURCES|ResourceSaver.FLAG_REPLACE_SUBRESOURCE_PATHS)

Minimal reproduction project

N/A

I think the problem is due to the signature of the ResourceSaver.save() method. For example in Object.connect(), the flags parameter is int, not the enum.

It looks like the reason is BitField<T>. More examples:

@tool
extends EditorScript

func _run() -> void:
    var button := Button.new()
    # Warnings: INT_AS_ENUM_WITHOUT_CAST, INT_AS_ENUM_WITHOUT_MATCH
    button.button_mask = MOUSE_BUTTON_MASK_LEFT | MOUSE_BUTTON_MASK_RIGHT

    # OK
    button.button_mask = MOUSE_BUTTON_MASK_LEFT

    var tp := TextParagraph.new()
    # Warnings: INT_AS_ENUM_WITHOUT_CAST, INT_AS_ENUM_WITHOUT_MATCH
    tp.justification_flags = TextServer.JUSTIFICATION_WORD_BOUND \
            | TextServer.JUSTIFICATION_CONSTRAIN_ELLIPSIS

    # OK
    tp.justification_flags = TextServer.JUSTIFICATION_WORD_BOUND

    # OK (int, not BitField<T>)
    connect(&"property_list_changed", func (): pass, CONNECT_DEFERRED | CONNECT_ONE_SHOT)

Closed by #75691 since I copied this small fix in the PR. #74641 renamed.
