What problem does this PR solve?

Part of https://github.com/pingcap/tidb-test/issues/1152

Problem Summary:

This fixes the session package to use the new APIs. It is expected to be backward compatible and covered by existing tests.

The bootstrap tasks between versions were not updated, as I'm not sure they will be accurately covered by unit tests to detect regressions.

What is changed and how it works?

New API usage.

Let us eliminate this function as it is only used in mustExec.

I will take a look in a followup PR. For now it looks like we are not getting into Execute/ExecuteInternal in the tests.

Well, maybe we don't need to change all the test code, as long as it does not affect the removal of the deprecated API.

I've reverted the tests so that they are still using Execute per the current plan. We can take a look at fixing master after all the cherry picks are complete.

Oh, I've met that kind of DATA RACE before...
ParseWithParams() called by multiple goroutines, and there is only one parser, thus the DATA RACE.

This time it's in another place rather than statistics

How do you think about creating a new session like:

func BootstrapSession(store kv.Storage) (*domain.Domain, error)
...
        se2, err := createSession(store)
        if err != nil {
                return nil, err
        }
        se3, err := createSession(store)
        if err != nil {
                return nil, err
        }
        // We should make the load bind-info loop before other loops which has internal SQL.
        // Because the internal SQL may access the global bind-info handler. As the result, the data race occurs here as the
        // LoadBindInfoLoop inits global bind-info handler.
        err = dom.LoadBindInfoLoop(se2, se3)
        if err != nil {
                return nil, err
        }

The DATA RACE is caused by here, in the test cases, multiple test case run loadCommonGlobalVariablesIfNeeded and they will use astNode.Accept(vistor) (which is not read-only operation) in statement rewriter.
