This macro does not do what is described. The only thing it actually does
control is whether or not the process's memory cache gets flushed when writing
to an address. It does not override the setting
`target.process.disable-memory-cache`.
Instead of making it work as intended, I chose to remove the macro. I don't see
much value in being able to override the setting with a preprocessor macro.
