FindQt[34]: Prefer matching versioned tool names

After finding qmake we search in QT_BINARY_DIR for the other Qt tools.
Try all versioned executable names before trying the plain executable name.
This makes it much more likely that if 2 different major versions are installed
in the same prefix CMake will be able to detect a proper set of tools.

variable_watch: Remove undocumented and redundant access type

The ALLOWED_UNKNOWN_VARIABLE_READ_ACCESS access type was switched on an
undocumented variable and its lookup caused an unnecessary performance
impact.  Remove it.
