[cssom-view] Remove "familiar with" check for move/resize methods

Closes #1725 by removing the usage of incumbent settings object. I could find no evidence of such a check in the Blink, Gecko, or WebKit codebases. Indeed, such a check should not generally be necessary, as (unlike, e.g., window.close()) these methods are not accessible cross-origin.

Also includes various changes for things that have updated in other specs:

* Use "this" instead of "context object"
* Use "string is" instead of "case-sensitive"
* Use "start node" and "start offset" instead of referring to properties of Range (or now, AbstractRange)
* Link to the correct "event loop" definition
* Remove redundant anchor blocks, as these days most definitions are properly exported

 Abstract: The APIs introduced by this specification provide authors with a way to inspect and manipulate the visual view of a document. This includes getting the position of element layout boxes, obtaining the width of the viewport through script, and also scrolling an element.
