[lldb][NFC] Remove TestFormats.py as is tests nothing

[teemperor]

Summary

This test tests nothing as it just creates a target and runs to main. It's also using pexpect
and its documentation and name don't fit its content.

[jingham]

Does anybody know what this was supposed to test?

[teemperor]

D66954 ninja'd this patch :(

[teemperor]

@jingham In D66954, Pavel digs into the history of the test a bit.

[jingham]

That was the only test that tested the "command regex" functionality. It was probably called TestFormats.py because somebody copied over a test without changing the file name since that name makes no sense.

[labath]

Actually, it looks like this test was committed with the regex stuff already being commented out (back in 2015/r228207), so the test never really tested anything..
