Add mb config for CrWinClang64(dbg).

Add mb config for CrWinClang64(dbg).

Since GN doesn't support swarming yet, update its corresponding
tester config to not use swarming. (If tester cycle time gets too high,
I will remove a few tests – we have enough gyp-based bots to not
really lose coverage.)

This won't have an effect until the recipe is updated to use
mb on this bot (which is blocked on the next ffmpeg roll).

lgtm w/ suggested change.

https://codereview.chromium.org/1170063002/diff/60001/tools/mb/mb_config.pyl
File tools/mb/mb_config.pyl (right):

https://codereview.chromium.org/1170063002/diff/60001/tools/mb/mb_config.pyl#...
tools/mb/mb_config.pyl:34: ['gn', 'clang', 'debug', 'shared',
'minimal_symbols'],
The style rules for this file aren't set in stone, but you can see I'm trying to
usually include "gyp" or "gn" in the name of the config, so that you can see at
a glance down in the bot mappings whether a given bot is using gyp or gn. I also
tend to leave out the platform if possible"

So, I might refactor this a bit as:

"gn_clang_debug_bot": ['gn', 'clang', 'debug_bot']

(shared and minimal symbols are mixed in automatically w/ debug_bot).

https://codereview.chromium.org/1170063002/diff/60001/tools/mb/mb_config.pyl#...
tools/mb/mb_config.pyl:179: },
and then rename this to just 'gn_clang_debug_bot'.

debug_bot also enables goma from what I understand (?), and goma doesn't work
with clang/win yet.

I added a comment about this. I can remove the win_ prefix, but other platforms
wouldn't want to use this config as they do want goma – let me know.

Ah, true.

Okay, I'm not coming up w/ a better name at the moment, so this lgtm as-is.
