The handling of keysym name guards (e.g. `#ifndef XK_Ydiaeresis`) was
incomplete and led to a missing keysym.
Make `sripts/makeheader` more robust to C macros handling.
Motivation: normalization of keysyms header files in `xorgproto`. See:
https://gitlab.freedesktop.org/xorg/proto/xorgproto/-/merge_requests/80
Improve `scripts/makeheader`:
- Simplify `evdev` and `XK_` substitution and improve alignment. Also, perform
some additional `XK_` substitutions in comments.
- Format with `black`.
- Add table of contents
- Add terminology section
- (WIP) Add Introduction to the format
- Improve the keycode section
- Improve the interpret section
- Add guide to create and use modifiers
- (WIP) Add actions documentation
- Add cross-references
- Add keysyms header to documentation
As of xorgproto commit 5dbb5b76597f [1], the 0x10081XXX keycode range is defined
for direct evdev kernel keycode mapping. For example, KEY_MACRO1 (0x290) is
mapped to 0x10081290. The format of the #define lines for these keys is
stable to allow for parsing:
#define XF86XK_FooBar _EVDEVK(0x123) /* optional comment */
Update our script so we detect these new lines. Our keysym generation is a
two-step process: makeheader and then makekeys. Replacing the key with its full
value in the makeheader script means we don't have to update makekeys to handle
the _EVDEVK macro and our header file is fully resolved.

These scripts generate source code that is committed to git and hence do
not really belong in the build system. A maintainer runs them as needed.
