Add url::Origin::GetURL() to convert Origins to URLs without reparsing

The previous canonical way to convert an Origin to a GURL was
to call GURL(origin.Serialize()). This is expensive and often in the
critical path of user perceived page loads. One such caller has
been converted to the new method, and the rest will be converted
in a followup patch.

Fix SchemeHostPort::GetURL() and add more tests

The implementation erroneously
 - Added an extra / to invalid URLs
 - Populated empty (len 0) url::Parsed components when they were empty in
   the class. Instead, they should have begin 0 and len -1.

Replace usage of GURL(origin.Serialize()) with origin.GetURL()

The bulk of this was via the following command:
git grep -l "GURL([a-zA-Z0-9\._]*\.Serialize())" | xargs sed -i \
 's/GURL(\([a-zA-Z0-9\._]*\)\.Serialize())/\1.GetURL()/g'

Which was then followed by a 'git cl format', and removing changes from
url unit tests, which check that this change has identical semantics.

renderer_host/media also had ConvertToGURL(Origin) methods
which were removed.

Unfortunately I did some more in-depth tracing/profiling and replacing

WebStringToGURL(web_security_origin.toString())

with

url::Origin(web_security_origin).GetURL()

Only produces marginal benefits (though it is a nicer API). I'm going to hold off on finishing the move until I can figure out a way to make the two steps (operator url::Origin and GetURL()) a bit faster.

Most of the time is spent doing string copies, and some policies that happens to be a bit slow.

Remove Origin->GURL conversion in DocumentSubresourceFilter

SameDomainOrHost was recently changed [1] to allow for comparing Origins
and GURLs, so we should remove the extra URL parsing here, which is a very
expensive operation.
