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.

description: undefined is not writable, should throw TypeError in strict mode
flags: [onlyStrict]
---*/
Reduce reliance on `fnGlobalObject.js` This harness function is not necessary in the majority of cases in which it is used. Remove its usage to simplify tests and decrease the amount of domain-specific knowledge necessary to contribute to the test suite. Persist the harness function itself for use by future tests for ES2015 modules (such a helper is necessary for tests that are interpreted as module code).

Enable strict mode for more built-in tests - Remove no longer needed noStrict flags. - Change tests to use propertyHelper.js for strict mode compatibility. - Add tests for return value of `delete` operator, e.g. `delete Array.prototype === false`. - Add non-writable tests for global NaN property. - Split some tests to run in strict mode. - Change tests with global `var length` declaration to use a different variable name for browser environments. - Merge duplicated tests symbol-data-property-configurable-non-strict and symbol-data-property-configurable-strict. - Merge duplicated tests symbol-data-property-writable-non-strict and symbol-data-property-writable-strict. - (And a small change in propertyHelper to reduce code duplication in function call.)
