Added image-orientation property
<!-- Please describe your changes on the following line: -->
Implemented as per the MDN documentation—I could not find a current CSS draft. I am not sure if this is the complete correct metadata for the longhand helper:
```
<%helpers:longhand name="image-orientation”
experimental=“True”
animatable=“False”>
```
Also I am not sure how to test this and would appreciate help in creating a testing strategy.

* `LonghandId` and `ShorthandId` are C-like enums
* `Atom` is used for the name of custom properties.
* `PropertyDeclarationId` is the identifier for `PropertyDeclaration`,
after parsing and shorthand expansion. (Longhand or custom property.)
* `PropertyId` represents any CSS property, e.g. in CSSOM.
(Longhand, shorthand, or custom.)
Using these instead of strings avoids some memory allocations and copies.
CookieStorage has been refactored to use HashMap with base domain as the
key. Values of hashmap is vector of cookies.
CookieStorage now has max_per_host which restricts maximum cookies that
can be added per base domain.
Cookie eviction doesnot take place if max_per_host is not reached.
Cookie eviction logic implemented here does following steps
1) Evict all expired cookies
2) Remove oldest accessed non-secure cookie If any
3) When no non-secure cookie exist, remove oldest accessed secure cookie
if new cookie being added is secure. Else ignore new cookie
Treat top-level number in calc() invalid
<!-- Please describe your changes on the following line: -->
This should probably considered as a temporary fix (for [bug 1321206](https://bugzilla.mozilla.org/show_bug.cgi?id=1321206)), to avoid assertion when trying to serialize calc value with only numbers. Certain properties (e.g. `line-height`) would eventually need to keep numbers inside calc.

Currently, CalcLengthOrPercentage doesn't actually keep the number value. If we don't treat it invalid, we can end up generating empty `calc()` value when one contains numbers (e.g. `calc(1)`), which would violate assertion elsewhere that `calc` must not be empty.

The change to the unit test is necessary because the resource thread is not
resilient against either of these Senders being dropped while the resource
thread is running. Before this change, it held clones of those senders itself
(public_setup_chan_clone, private_setup_chan_clone).
Only allow border-image-outset to use non-negative numbers.
Restricts border-image-outline to only allow positive values.
