Yukihiro "Matz" Matsumoto 7e26271a01 mruby-string-ext: hoist RSTRING_PTR calls in String#tr ...

Optimizes String#tr by hoisting RSTRING_PTR calls for pattern strings
outside the main loop to avoid repeated conditional checks.

Before: 2 RSTRING_PTR calls per iteration (once for each pattern)
After: 2 RSTRING_PTR calls total (pointers cached outside loop)

String#tr is commonly used for character transliteration and this
optimization provides measurable improvement for long strings.
