Provide useful defaults for Android logcat output
These changes integrate the stdout/stderr redirection from 0e80cfbcee/cargo-apk/injected-glue/lib.rs (L240-L303), and set up the default RUST_LOG filters so that useful JS errors and GL errors appear in the logcat output. I have verified that thread panics appear in output as well (without backtraces, sadly) by visiting https://acid3.acidtests.org.

Add mach command to setup remote debugging on Android devices.
This removes any need to fiddle with search paths for source files and makes the experience of remote debugging much less frustrating. I've tried this on a Pixel, Pixel 2, and emulator and successfully set breakpoints and investigated variables on all of them. The APP_ABI changes are necessary to prevent ndk-gdb from thinking that the build is arm64 when it's not.

Rewrite Taskcluster integration
This rewrites this repository’s integration with Taskcluster to have a decision task that runs an in-tree Python script to schedule a graph of other tasks with inter-dependencies, saved build artifacts, Docker images built from in-tree `Dockerfile`s, etc. This also adds support fail daily tasks, run automatically every 24 hours. See `etc/ci/taskcluster/README.md` for more details.
Example of a green build with web-platform-tests enabled: https://tools.taskcluster.net/groups/aDL0pUBkSmuhezT1OF80_g
For now this PR only enables one task, equivalent to Buildbot’s `linux-dev` job. (Running Tidy and other linting tools, compiling in debug mode, and running unit tests.) At this time Homu does **not** yet block PRs from merging on a successful result from Taskcluster, but I plan to do this soon after this PR lands.
