Subject: libcamera: internal: Convert to pragma once

Remove the verbose #ifndef/#define/#endif pattern for maintaining
header idempotency, and replace it with a simple #pragma once.

This simplifies the headers, and prevents redundant changes when
header files get moved.

Tracepoints.h.in is not modified to use the pragma as it requires
self-inclusion.
