Fix Image CowData crash when baking large lightmaps

Browse Source 
This switches to 64-bit integers in select locations of the Image
class, so that image resolutions of 16384×16384 (used by
lightmap texture arrays) can be used properly. Values that are larger
should also work.

VRAM compression is also supported, although most VRAM-compressed
formats are limited to individual slices of 16384×16384. WebP
is limited to 16383×16383 due to format limitations.

Validate extension JSON: Error: Field 'classes/Sprite3D/properties/frame_coords': type changed value in new API, from "Vector2" to "Vector2i".
The type was wrong to begin with and has been corrected. Vector2 and Vector2i are convertible, so it should be compatible.

Validate extension JSON: Error: Field 'classes/Image/methods/get_mipmap_offset/return_value': meta changed value in new API, from "int32" to "int64".
Type changed to int64_t to support baking large lightmaps.
No compatibility method needed, both GDExtension and C# generate it as int64_t anyway.
