I couldn't find a tool that enforces it, so I went the manual route:
```
find -name "thirdparty" -prune \
-o -name "*.cpp" -o -name "*.h" -o -name "*.m" -o -name "*.mm" \
-o -name "*.glsl" > files
perl -0777 -pi -e 's/\n}\n([^#])/\n}\n\n\1/g' $(cat files)
misc/scripts/fix_style.sh -c
```
This adds a newline after all `}` on the first column, unless they
are followed by `#` (typically `#endif`). This leads to having lots
of places with two lines between function/class definitions, but
clang-format then fixes it as we enforce max one line of separation.
This doesn't fix potential occurrences of function definitions which
are indented (e.g. for a helper class defined in a .cpp), but it's
better than nothing. Also can't be made to run easily on CI/hooks so
we'll have to be careful with new code.
Part of #33027.
Which means that reduz' beloved style which we all became used to
will now be changed automatically to remove the first empty line.
This makes us lean closer to 1TBS (the one true brace style) instead
of hybridating it with some Allman-inspired spacing.
There's still the case of braces around single-statement blocks that
needs to be addressed (but clang-format can't help with that, but
clang-tidy may if we agree about it).

This reverts commit ec7b481170.
This was wrong, `d` is not a distance but the `d` constant in the
parametric equation `ax + by + cz = d` describing the plane.
A vertical FOV of 75 degrees is roughly equivalent to a 91 degree
horizontal FOV on a 4:3 display (~107.51 degrees on 16:9),
which is close to the typical default FOV used in PC games.
Note that this doesn't apply to the in-editor camera which keeps its
FOV to 70. This is because it doesn't display in fullscreen;
its viewport only displays in the center of the editor (roughly).
This means the viewport won't cover the viewer's eyes as much. Therefore,
the editor camera FOV should be slightly lower to account for this.
Since this changes the default value, this may break existing projects
slightly.
For the record, this was already done in
https://github.com/godotengine/godot-demo-projects/pull/260
for the official demo projects.
