Subject: [PATCH] winrt: Fix API usage certification

According to MSDN Tls* is inline replaced by Fls* on Windows (Phone) 8.1
and beyond.
However, this does not seem to be the case for Windows 10. An
application links against Tls* and the certification step fails due to
using non-allowed APIs.

Hence we do the inline replacement manually. QThreadStorage and QThread
tests continue to work, so it seems to be an oversight by Microsoft.

Task-number: QTBUG-50292
Change-Id: Ice1b6e54fcee238c94af5c6fb1753d903db7476d
