[clang-format] Re-land: Fixup #include guard indents after parseFile()
Summary:
When a preprocessor indent closes after the last line of normal code we do not
correctly fixup include guard indents. For example:
#ifndef HEADER_H
#define HEADER_H
#if 1
int i;
# define A 0
#endif
#endif
incorrectly reformats to:
#ifndef HEADER_H
#define HEADER_H
#if 1
int i;
# define A 0
# endif
#endif
To resolve this issue we must fixup levels after parseFile(). Delaying
the fixup introduces a new state, so consolidate include guard search
state into an enum.
