kconfig: support append assignment operator
Support += operator. This appends a space and the text on the righthand side to a variable. The timing of the evaluation of the righthand side depends on the flavor of the variable. If the lefthand side was originally defined as a simple variable, the righthand side is expanded immediately. Otherwise, the expansion is deferred. Appending something to an undefined variable results in a recursive variable. To implement this, we need to remember the flavor of variables.
