Built-in data types: vector, matrix (tensor)

Extracted from: https://github.com/comfyanonymous/ComfyUI/issues/8821

### Feature Idea

A huge part of image processing relies on linear algebra. Currently, each node author willing to do it has to reinvent the wheel.
Everyone would benefit if standard-size vectors/matrices were built-in types:
- vector[2/3/4] (maybe even vector1 - just for the sake of consistency)
- matrix3/4
- for both - an int and float version
- with frontend widgets existing out of the box
- Ideally, with an ability to link EITHER pre-built matrix/vector connection or floats/ints directly into components. If hard to implement, simple conversion nodes (floats > vector and vice versa) is perfectly fine, too.
