Move LINT_NO_COMMIT from ArcanistTextLinter to a new linter

Summary: I don't feel that this linter rule belongs in the `ArcanistTextLinter`. In fact, this linter rule is quite similar to the rules provided by `ArcanistGeneratedLinter` and `ArcanistNoLintLinter` and these classes could possibly be consolidated. I have moved this linter rule to a standalone `ArcanistCommitLinter` class (which could possibly do additional lints in the future).

Test Plan: Moved existing test cases.
