provider/aws: Allow creating aws_codecommit repository outside of us-east-1

[stack72]

Fixes #11175

Because of a previous limitation that codecommit only ran in us-east-1,
we hard coded the session under which it should run. This has caused the
repository to be spun up in the wrong region regardless of what region
was passed to the provider

make testacc TEST=./builtin/providers/aws TESTARGS='-run=TestAccAWSCodeCommitRepository_'
