libcamera: controls: Construct Span with size for array controls
The ControlList::set() function overload used for array controls
constructs a Span from an initializer list. It doesn't specify the Span
size explicitly, which results in a dynamic extent Span being
constructed. That causes a compilation failure for fixed-size array
controls, as they are defined as Control<T> with T being a fixed-extent
Span, and conversion from a dynamic-extent to fixed-extent Span when
calling ControlValue::set() can't be implicit.
Fix this by constructing the Span using the size of the control, which
resolves to a fixed-extent and dynamic-extent Span for fixed-size and
dynamic-size array controls respectively. The ControlList::set()
function that takes an initializer list can then be used for fixed-size
array controls.
