Subject: libcamera: controls: Generate and use fixed-sized Span types

Define Span types explicitly as either variable- or fixed-sized. This
introduces a new convention for defining Span dimensions in the property
and control value definitions and generates Span types as variable-sized
Span<T> or as fixed-sized Span<T,N>.
