migrate x/params to use app wiring

[tac0turtle]

• add app wiring functions
• define own app.yml
• decouple from simapp

ref #12023

[facundomedica]

This is being worked on here #11924

[aaronc]

We need to distinguish two phases:

• app wiring setup (feat: start app wiring with runtime and x/params modules #11924)
• no dependency on simapp

[JeancarloBarrios]

@aaronc can we start on decoupling from simapp or should we wait for other modules?
