[JSC] Remove unnecessary memmove and strlen for dragonbox ToShortest
https://bugs.webkit.org/show_bug.cgi?id=278703
rdar://134763943
Reviewed by Yijia Huang.
1. dragonbox::ToExponential / dragonbox::ToShortest were doing unnecessary
strlen. This patch removes it.
2. FastStringifier employs dragonbox::to_char_n directly so that we remove one
more unnecessary memmove observed in the profile.
