cmake: Generate cvc4_export.h and set visibility to hidden. (#6139)

The build system (cmake) will automatically generate an export header
cvc4_export.h, which makes sure that the correct export features are
defined depending on the compiler and target platform. The macro CVC4_EXPORT
replaces CVC4_PUBLIC and its usage is reduced by 2/3.
