CSA::AllocateSeq{One,Two}ByteString used its own home-grown handling to allocate very large strings. This CL refactors both methods to use AllocationFlags::kAllowLargeObjectAllocation instead. Callers now need to specify explicitly if large-object allocation is possible or not.

This is mainly to enable optimization of case-insensitive maps, where we see the pattern if (m.has(key.toLowerCase())) { return m.get(key.toLowerCase()) } ...

Restore original behavior in that strings are deduplicated in lower-case conversion (i.e. if the string is already lower-case, the original string is returned). BUG=v8:6353,v8:6412 Review-Url: https://codereview.chromium.org/2891853004 Cr-Commit-Position: refs/heads/master@{#45391}

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.
