QString: mark inline to{U,}LongLong() for inlining in Qt 7

The original implementation of the toIntegral_helper() called these two
functions, before we added the out-of-line non-template
toIntegral_helper() overloads taking QStringView for Qt 5.15 in commit
f1cbc3c9d24024b6bdd8d0346de9d7e548133459. They should have been inlined
in Qt 6.0, but no one noticed this.
