ENH: Define STRINGS cache entry property

This property defines a list of values for a cache entry of type STRING.
A CMake GUI may optionally use a drop-down selection widget for the
entry instead of a generic text entry field.  We do not enforce that the
value of the entry match one of the strings listed.
