qmltyperegistrar: refactor FILE* to QTextStream

Replace the use of FILE* in qqmltyperegistrar to QTextStream to make
qqmltyperegistrar more easy to use, as getting a FILE* to a temporary
file on any qt supported platform seems to be really complicated.

Uses QString for all QTextStream related operations as it formats
char16_t* as pointer addresses.
