For making our code clearer by the stronger type check, we should change the anonymous enum for NS_TEXTRANGE_* to enum class whose name is "TextRangeType" and whose type is "RawTextRangeType" which is an alias of uint8_t. Additionally, this also adds some utility methods for them. Note that some lines which are changed by this patch become over 80 characters but it will be fixed by the following patches.
