Data from 99th percentile power investigation show that FindFirstPageURLForHost can be quite expensive in some cases.
It seems that we can make it significantly faster by optimizing
the SQL query in it.
This CL removes the use of LIKE operator and substitutes it with
string comparisons. Local synthetic test shows ~20x speed improvement
for this query.

This function is needed by favicons, which I plan to move to
//components/favicons. To avoid circular deps I'm moving the
function into //components/database_utils. I would have liked
to avoid a component purely for this function, but I couldn't
find a better place.
