tests: refactoring (cosmos#198)

* test refactoring

evmd as separate package
- we can make sure more clean dependency: only evmd -> evmd allows. not vice versa.

test re-structuring
- tests using network + evmd moved into evm/tests/integration
- test file names are changed from *_test.go to test_*.go, so any client chains can leverage cosmos/evm's test suites with their own application

refactoring
- all integration tests in evm uses EvmApp interface. so it allows other client application can leverage cosmos/evm's test suites.
- evmd implements methods of EvmApp
- separate Erc20Keeper interface to avoid cyclic import between erc20/keeper and precompiles/erc20
- change backend member variables to public. this is for making testing refactoring easier. if there are some security concern, we should consider introducing getters.

 removed un-used files

* upstream merge and resolve conflicts

* fix lints & ci

removed already migrated test also

* fix ci

* fix lint issues

* fix ginkgo issues and update testing ci, makefile

* gci formatted and re-organize authz test

* add missed test case

* fix ci issue

* erc20 cyclic dependencies resolved

* chore: typo

* chore: package name

* chore: test convention

* chore: test convention

* chore: align convention

* un-do un-necessary change

pb files should not be touched

* re-organize ibc testing dir and make ibc testsing using EvmApp, not evmd

* fix Makefile

* change go mod name to github.com/cosmos/evm/evmd

* merge main & resolve conflicts

* fix lint
