Previously (since f0e95769), this toLowerCase fast-path assumed
it would only see one-byte flat contents. Unfortunately, it's
possible to have a one-byte sliced string that has a two-byte parent.
This CL ensures that String.p.toLowerCase handles such cases
correctly.

This CL migrates the CPP builtin to CSA with fast paths for strings
that can be unpacked to direct one-byte strings. Short strings are
handled directly in CSA, others need to call into C for conversion.
Microbenchmarks for "abcd".toLowerCase() show speedups of 2.5x.
