The `Context` currently contains a `strict` flag that indicates is global strict mode is active. This is redundant to the strict flag that is set on every function and causes some non spec compliant situations. This pull request removes the strict flag from `Context` and fixes some resulting errors.
Detailed changes:
- Remove strict flag from `Context`
- Make 262 tester compliant with the strict section in [test262/INTERPRETING.md](2e7cdfbe18/INTERPRETING.md (strict-mode))
- Make 262 tester compliant with the `raw` flag in [test262/INTERPRETING.md](2e7cdfbe18/INTERPRETING.md (flags))
- Allow function declarations in strict mode
- Fix parser flag propagation for classes
- Move some early errors from the lexer to the parser
- Add / fix some early errors for 'arguments' and 'eval' identifier usage in strict mode
- Refactor `ArrayLiteral` parser for readability and correct early errors
