Standardise Naming of has flags

We should standardise has flag naming to be more expressive. The ideally should refer to the macro standard of which they were introduced in.

For example:

• html5- for items that were introduced as part of HTML5
• dom3- for items that were introduced as W3C DOM Level 3 Specification
• es5- for items that were introduced as part of ECMAScript 5
• es6- for items that were introduced as part of ECMAScript 6/2015
• es7- for items that are likely to be ratified as part of ECMAScript 7 (e.g. Object.observe)
• css3- for items that were introduced as part of CSS3

We have started following this and most of this was accomplished during the refactor that broke dojo/shim out of dojo/core and we should continue to do this.
