The libcamera public API uses 'stride' to refer to the line stride.
Rename the SDLTexture::pitch_ member variable for consistency.

The SDL_PixelFormatEnum type has been introduced in libsdl by
1a4c0d4e17e6 ("Fixed bug 4377 - SDL_PIXELFORMAT enum is anonymous, which
prevents its use in a templated function") which is only available after
release 2.0.10 of the library.
Debian 10 ships libsdl at version 2.0.9 and building cam with sdl
support there fails with error:
./src/cam/sdl_texture.h:27:8: error: ‘SDL_PixelFormatEnum’ does not name
a type; did you mean ‘SDL_PixelFormat’?
Fix that by using the base type uint32_t in place of
SDL_PixelFormatEnum.

This adds more portability to existing cam sinks. You can pass a
YUYV camera buffer and SDL will handle the pixel buffer conversion
to the display. This allows cam reference implementation to display
images on VMs, Mac M1, Raspberry Pi, etc. This also enables cam
reference implementation, to run as a desktop application in Wayland or
X11. SDL also has support for Android and ChromeOS which has not been
tested. Also tested on simpledrm Raspberry Pi 4 framebuffer
successfully where existing kms sink did not work. Can also be used as
kmsdrm sink. Only supports one camera stream at present.
