[lldb][NFC] Remove unused macro ENABLE_MEMORY_CACHING

[bulbazord]

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.
