replace CharUnicodeInfo with that of referencesource and update runtime.

CharUnicodeInfo had conversion methods for uppercase/lowercase conversion, and they are actually used by TextInfo. So moved them. Then added another icall for "lite" version of internal character table loader. The new CharUnicodeInfo depends on "charinfo.nlp" resource file, which does not exist in referencesource but can be generated by coreclr build tools (as src/mscorlib/src/System/Globalization/Tables/CharInfo.nlp). The coreclr rev. that built this specific checkin was c4eb037.
