Normalize testcase format This commit normalizes the test case format used across test262. It applies the following transformations: * Convert to YAML for frontmatter * Remove of trailing whitespace * Replace /r/n with /n except in chapters 6 and 7. * Copyright header always uses // comments * new includes attribute replaces $INCLUDE * No implicit assumptions about test environment other than $ERROR. Everything else appears in the include array. This includes "runTestCase" which is now included in a substantial number of tests.
