clang-format: Regroup sort orders

Utilise the clang-format header sort to provide a regex based pattern
match for our header inclusion coding style.

The rules are updated to match as closely as possible the existing
practices and the documentation is updated accordingly.

that header file shall be included first in order to ensure it is
self-contained.
While the following list is extensive, it documents the expected behaviour
defined by the clang-format configuration and tooling should assist with
ordering.
The headers shall be grouped and ordered as follows:
1. The header declaring the API being implemented (if any)
2. The C and C++ system and standard library headers
3. Other libraries' headers, with one group per library
4. Other project's headers
3. Linux kernel headers
4. The libcamera base private header if required
5. The libcamera base library headers
6. The libcamera public API headers
7. The libcamera IPA interfaces
8. The internal libcamera headers
9. Other libraries' headers, with one group per library
10. Local headers grouped by subdirectory
11. Any local headers
Groups of headers shall be separated by a single blank line. Headers within
each group shall be sorted alphabetically.
System and library headers shall be included with angle brackets. Project
headers shall be included with angle brackets for the libcamera public API
headers, and with double quotes for other libcamera headers.
