'read_registry' is not a recognized replace function

Since Qt 5.12.1, a handy replace function named read_registry() was added to qmake on Windows host.

However, it seems that the Qt Creator's built-in project parser does not support this function. Every time when I open or save a pro file which contains the read_registry() function, the "General Message" panel will print a warning:

<path to pro file>: 'read_registry' is not a recognized replace function.
