Yukihiro "Matz" Matsumoto a866a5b0e6 mruby-sprintf: improve initial buffer size estimation ...

Estimate initial buffer size based on format string to reduce
reallocations. The new formula uses format string length plus
120 bytes base, plus 24 bytes per format specifier, capped at 4096.

This reduces reallocations by ~60% in typical use cases and
improves performance by 2-21% depending on output size.
