WebRTC: Rename trybots and add compile-only configs.

WebRTC: Rename trybots and add compile-only configs.

- Rename Debug trybots to use _dbg suffix.
- Add compile-only bots.
- Add missing x64 Debug configurations (that will not be run by default).

This should improve our flexibility and allows to run
compile-only trybots for Debug configuration, which should reduce
the CQ load a bit.

Summary of changes:
New bots:
win_compile_dbg
win_compile_rel
win_compile_x64_dbg
win_compile_x64_rel
mac_compile_dbg
mac_compile_rel
mac_compile_x64_dbg
mac_compile_x64_rel
linux_compile_dbg
linux_compile_rel
android_compile_dbg
android_compile_rel
android_compile_arm64_dbg
android_compile_arm64_rel

New debug configurations (were missing):
mac_x64_dbg
win_x64_dbg

Renamed trybots for consistency:
win -> win_dbg
win_x64_gn -> win_x64_gn_dbg
mac -> mac_dbg
mac_x64_gn -> mac_x64_gn_dbg
ios -> ios_dbg
ios_arm64 -> ios_arm64_dbg
ios32_sim -> ios32_sim_dbg
ios64_sim -> ios64_sim_dbg
linux -> linux_dbg
linux_gn -> linux_gn_dbg
android -> android_dbg
android_clang -> android_clang_dbg
android_gn -> android_gn_dbg

I decided to have these ones join the larger pool for better throughput. Only
the Light one is part of the CQ currently.

LGTM if presubmit passes - sorry for the late response. This one fell through
the cracks...

Wonder if you need to tweak these numbers at some point?

Acknowledged. Tiny disadvantage might be that the win-drmemory checkout will be
created on all the other slaves too. And the probability for reusing an
incremental build gets lower with the increasing number of slaves.

Replied..

I'll probably update the tryserver manually for this one, so I can rename a lot
of build log directories on the master before starting it up with the new config
(so we don't loose history)

I guess we might at some point, but I haven't seen it higher than 100 except on
one tryserver.

That's true, but compilation is taking up a small portion of the full build
(except for the new compile-only trybots of course, but anyway). Let's try this
for now.
