First pass at adding http/backend cache events to the NetLog.

Adds sources and events for ActiveCacheEntry and EntryImpl 
objects, as well as adding cache read/write events to 
HttpCacheTransactions. Most new read/write events are 
only logged when NetLog logging mode is set to log all events. 

Also, net-internals now merges begin and end events that have 
parameters, as long as only one of them has parameters. 
I think this increases readability, at the cost of making 
it a little more difficult to follow timings with just the "st" 
values. 

BUG=59382
TEST=none yet, other than updates to existing tests.
