qmake: Change source identifier type in ProString

Browse Source 
The strings remember in which file they were created/assigned.

However, this used a non-counting reference to a ProFile, which could
become dangling. If a subsequent ProFile re-used the exact same address,
a string's source would be mis-identified, which would be fatal in
conjunction with discard_from().

Since we actually need only a unique id for comparison, let's use an
integer for that.

comment on cherry-pick: this is actually a lot more than a cherry-pick,
because the file ids need to be aware of the dual VFS which was
concurrently introduced on the qtc side.
