<pre>Separate PrivateClickMeasurement database from ResourceLoadStatistics database and add SPI to set its location
https://bugs.webkit.org/show_bug.cgi?id=229527

Source/WebKit:

This will be used by rdar://80806283

In order to do this, I moved common code to DatabaseUtilities and moved the PCM logic from ResourceLoadStatisticsDatabaseStore
to a new class.  It puts the data in a different file in the same directory unless SPI tells it to put it in a different directory.

The biggest functional change I needed to do was to make a PCMObservedDomains table in the new DB instead of an ObservedDomains table,
which contained more information than I needed.  I need just an index and a list of domains.

Another slight implementation change is that instead of checking isEphemeral in WebResourceLoadStatisticsStore, I just pass an empty
String to the Store if it's ephemeral, which causes no DB to be created, which causes equivalent behavior.

I also moved the debug message broadcasting to PrivateClickMeasurementManager::attribute in order to make the Database object not
need to know about the NetworkProcess and not need to keep state of whether debug mode is enabled.  Database::attributePrivateClickMeasurement
now returns a DebugInfo object and PrivateClickMeasurementManager::attribute checks whether debug mode is enabled and broadcasts the messages.

I added a few calls to PrivateClickMeasurement::isolatedCopy when moving an PrivateClickMeasurement object to another thread.

I added a CompletionHandler to clearPrivateClickMeasurement and clearPrivateClickMeasurementForRegistrableDomain
so that clearing website data doesn't say it's done until it's done.

An even smaller change is I added a "ForTesting" suffix on some function names of functions that are only used in tests.

The rest of this patch just moves code from one location to another.

I still need to implement migrating data from the old DB to the new DB.  I'll do that in another patch soon.

+
+        Separate PrivateClickMeasurement database from ResourceLoadStatistics database and add SPI to set its location
+        https://bugs.webkit.org/show_bug.cgi?id=229527
+
+        Reviewed by Kate Cheney.
+
+        This will be used by rdar://80806283
+
+        In order to do this, I moved common code to DatabaseUtilities and moved the PCM logic from ResourceLoadStatisticsDatabaseStore
+        to a new class.  It puts the data in a different file in the same directory unless SPI tells it to put it in a different directory.
+
+        The biggest functional change I needed to do was to make a PCMObservedDomains table in the new DB instead of an ObservedDomains table,
+        which contained more information than I needed.  I need just an index and a list of domains.
+
+        Another slight implementation change is that instead of checking isEphemeral in WebResourceLoadStatisticsStore, I just pass an empty
+        String to the Store if it's ephemeral, which causes no DB to be created, which causes equivalent behavior.
+
+        I also moved the debug message broadcasting to PrivateClickMeasurementManager::attribute in order to make the Database object not
+        need to know about the NetworkProcess and not need to keep state of whether debug mode is enabled.  Database::attributePrivateClickMeasurement
+        now returns a DebugInfo object and PrivateClickMeasurementManager::attribute checks whether debug mode is enabled and broadcasts the messages.
+
+        I added a few calls to PrivateClickMeasurement::isolatedCopy when moving an PrivateClickMeasurement object to another thread.
+
+        I added a CompletionHandler to clearPrivateClickMeasurement and clearPrivateClickMeasurementForRegistrableDomain
+        so that clearing website data doesn't say it's done until it's done.
+
+        An even smaller change is I added a "ForTesting" suffix on some function names of functions that are only used in tests.
+
+        The rest of this patch just moves code from one location to another.
+
+        I still need to implement migrating data from the old DB to the new DB.  I'll do that in another patch soon.
