Tests/Tokenizer: tests to ensure scope is set correctly for T_SWITCH
This commit copies, with some non-structural modifications, a sniff test to the tokenizer tests. The original test was added in b24b96b, part of squizlabs/PHP_CodeSniffer#497. b24b96b introduced a test to InlineControlStructureUnitTest.php as there were no Tokenizer tests back then. It was added to ensure that Tokenizer::recurseScopeMap() would correctly add scope information to the `T_SWITCH` token when handling a `switch` that uses the alternative syntax. This commit also adds a test to ensure the scope is correctly set when using the normal switch syntax. This was not part of b24b96b, but it is relevant anyway, as no other tokenizer test covers this part. Since the InlineControlStructure sniff doesn't listen for the `T_SWITCH` token anymore (see baa4f65), the original test added in b24b96b became useless and thus was refactored to use a different control structure. The sniff test was kept as testing code that uses a control structure, and opening and closing PHP tags is an interesting case not covered in other tests.
