Sets `AlignOperands` to `DontAlign`.
`clang-format` developers seem to mostly care about space-based indentation and
every other version of clang-format breaks the bad mismatch of tabs and spaces
that it seems to use for operand alignment. So it's better without, so that it
respects our two-tabs `ContinuationIndentWidth`.
Disable minimum amount of spaces in comment prefix for now, as it otherwise
modifies the whole codebase. That's something we probably want to use as it
matches our convention, but we should look into fully converting these
comments to our style guide at the same time.
(cherry picked from commit 63544c3a9d)
Adapted some parameters to fit the de facto Godot style as closely as possible
(tab indentation, long lines with no wrapping - for now -, indented case labels,
left-aligned pointer operators).
