Refactor str_succ_bang for in-place modification
...
This commit refactors the str_succ_bang function in mrbgems/mruby-string-ext/src/string.c to perform string succession in-place.
The previous implementation used an intermediate temporary string, which incurred memory and performance overhead.
This change aims to reduce memory usage and improve performance by modifying the string buffer directly, using mrb_str_resize and memmove when prepending characters is necessary (e.g., '9' -> '10').
Formatting changes (newlines before 'else') have also been applied as per user request.

mruby.h: rename ASCII flag to SINGLE_BYTE
...
This flag means all the characters in the string can be represented by a
single byte, i.e., the string does not contain any multi-byte character.
Those characters are likely ASCII characters, but may be a part of broken
UTF-8 sequence, so the term 'ASCII' is not sufficient.
