FastSimRocketConfig with no TLMonitors

[joonho3020]

Due to the active chiplet development, the complexity of TLMonitors has exploded 😢 .
This causes RTL simulation speed to go down by 2x which is a significant regression.
We want to add a example configuration where we remove the TLMonitors and add some documentation of this phenomenon.

I noticed that there is nowhere in the docs that has a concrete example of overriding the default CONFIG. Maybe this isn't necessary... but perhaps one line can be added:

To simulate this config, you can run:

`make run-binary CONFIG=FastRTLSimRocketConfig BINARY=... LOADMEM=1`
