Previously we would only enable by default when `parseArgs` was called. However this wouldn't enable it for clients such as LLDB, who provide their own invocation. Switch the default to `true` in the `LangOptions`, and remove some redundant uses of `-enable-experimental-string-processing`. The frontend flag remains, as it may be useful to disable. rdar://107419385 rdar://101765556
