Subject: [PATCH 1/2] [clang-format] Introduce "ReflowComments: IndentOnly" to
re-indent comments without breaking internal structure (think Doxygen).
* Convert `ReflowComments` from boolean into a new `enum` which can take on the value `RCS_Never`, `RCS_IndentOnly`, or `RCS_Always`. The first one is equivalent to the old `false`, the third one is `true`, and the middle one means that multiline comments should only have their indentation corrected, which is what Doxygen users will want.
* Preserve backward compatibility while parsing `ReflowComments`.
