Reduce over-allocation in TextCodecUTF8::encodeUTF8() for 8-bit strings
https://bugs.webkit.org/show_bug.cgi?id=311345
Reviewed by Anne van Kesteren.
TextCodecUTF8::encodeUTF8() unconditionally allocated 3x the input
length for the output buffer. The 3x multiplier is correct for 16-bit
strings (BMP characters can expand to 3 UTF-8 bytes per code unit),
but for 8-bit Latin1 strings the maximum expansion is only 2x
(characters 0x80-0xFF encode as 2-byte UTF-8 sequences).
