Remove gaia (cosmos#4347)

Gaia is removed from cosmos-sdk repository.

Few changes were required to make sure no packages depend on gaia subpackages.

CI config is amended accordingly.

Unnecessary targets are removed from Makefile.

Simulations run through a lightweight version of gaia renamed to simapp.

Closes: cosmos#4104
