m3: move res out of *-watch-v36 dir

The trunk_staging sdk version is set to large dummy value, so it looks
like it always work no matter what sdk version the device is using. But
"next" is using the real sdk version value, so, the -v36 will be work on
"next" build. Currently "next" is still using v35, therefore, v36
resource won't be included in the image.

Since we isolate the Wear Material3 style and resources from the global
platform ones, we can use feature flags and Compat to control them.
This CL will move everything from *-watch-v36 dir to base dir, the ones
without qualifiers. See car's example:
frameworks/base/core/res/res/values/dimens_car.xml
