cam: sdl_sink: Pass a Span<const uint8_t> to SDLTexture::update()
The SDLTexture::update() function isn't meant to modify the data it receives. Make the Span type const to ensure this at compile time. While at it, pass the Span by value instead of reference, as a Span is only a pointer and size, which will fit in registers and will avoid pointer dereferences in the callee.
