Avoid interspersed length/value buffer in CPDF_ToUnicodeMap.

Somewhat less memory efficient, but simpler and safer, avoids casting
character values to lengths. Avoids allocations and copies from buffer
when returning multi-char strings.

-- Fix some IWYU in headers.
-- Explicitly construct single-char strings.
-- Rename GetUnicode() method to describe what it actually returns.
