add virtual ~Effect()

Today we make an sk_sp<Effect> from an sk_sp<EffectImpl>.
But when the sk_sp<Effect> dies, it calls ~Effect(), not ~EffectImpl().
Making ~Effect() virtual fixes this.

This should make our Google3 tests sized-delete clean, unblocking those folks.

Swarming bots: setup for skipping download of build products

Turns out it's pretty easy to pass the compile outputs to the test task by just adding the hash to the "includes" list in the .isolated file.  So the flow is:
1. Isolate skia repo
2. Run compile task, record hash of results
3. Isolate test inputs for DM. This writes a .isolated file
4. Edit the .isolated file from #3 to include the hash from #2
5. Upload the modified .isolated file to the isolate server
6. Trigger the swarming task for DM
7. Wait for DM task to finish, download results from isolate server
8. Upload results to GS as normal

I expect the swarming bots to break when this is committed due to the moved out directory.  The associated recipe change will fix them.

Force tiles in SampleApp to integer boundaries.

The current behavior is to create tiles from the rounded ideal tile size,
tell the tile that it's upper left pixel is at the ideal location, and
then draw those tiles at the ideal locations. As a result, the tiles are
be out of phase with each other internally and then actually drawn at
the rounded pixel location instead of the ideal location.

The new behavior is to always round up to get the tile size, make the
tile translation an integer offset, and then draw at the exact pixel.

This also modifies SampleApp to use the numeric keypad to provide an
extra manual 1/32 pixel translation for fine grained movement.

Revert of respect sRGB when converting from sk to gr configs (patchset #1 id:1 of https://codereview.chromium.org/1756913003/ )

Reason for revert:
Two major regressions from this change:
- Mac images may end up too bright, if they're correctly tagged as sRGB. That's a sub-set of a much larger issue where L32 mode needs to suppress sRGB -> Linear conversion of pretty much everything.
- Various low-end GPUs (Mali400 Android, iPad4) don't render in sRGB at all, causing tests to produce no output at all.
