patch 9.1.1051: tests: no support for env variables when running Vim in terminal

Problem:  tests: no support for env variables when running Vim in
          terminal
Solution: support the "env" argument in RunVimInTerminal(),
          close swapfiles properly in test_termcodes,
          use CheckFeature in test_termencoding
