* If target:esnext,then useDefineForClassFields: true will now be the default. * Added error if a private identifier is used in a static a initializer if target:ESNext and useDefineForClassFields:false. * Added test for new useDefineForClassFields default and error message. * Fixed tests after changing the default of useDefineForClassFields to true for target esnext * Fixed code review suggestions. * Updated error message. * Added missing static check for the containing property. Fixed other code review issues.
