Allow setting default input bandwidth limit

Make the CSS and HTML content filters more robust against accidental modification.

This makes all the collections of allowed tags/selectors/etc 'public static final' immutable collections.
For readability, this uses empty collection instead of null in CSS filter where this does not change semantics (e.g. in parserExpressions).
Ban :visited pseudoclass in CSS filter as it is deemed unsafe.

:visited may change the way a site is displayed based on the browser history of a user, and history information might be disclosed through trusted plugins.
This is described in detail in the comments of ElementInfo.BANNED_PSEUDOCLASS.

We make :visited banned rather than invalid, since the spec prescribes to ignore the entire declaration if a selector is _invalid_, which presents usability issues with disjunctive selectors.
Instead, we ignore only the selector involved if it is deemed valid yet banned.

This also updates CSSParserTest with correct expected results for :visited.
Add more tests on banned selectors.
Use tabs instead of spaces where this fixes indentation.

This does not fix all indentation issues, but it does fix those introduced in this branch.

Separate display and SFS/FCP Option representation

Specifically sizes should only be formatted with size units when
displayed to the end user. Conflating display and data transfer/storage
representation, if nothing else, makes FCP more difficult to use. A
bandwidth limit or store size must be parsed for units instead of used
as a number of bytes.
