* Add linux/arm64 support to bazel rules
* Make linux arm64 sha optional and PR feedback
Not all releases have linux shas. Use getattr to default to no sha if none was
present. This way non linux arm64 builds should not fail.
* Update linux arm64 sha for 3.1.33
This is the latest arm64 release according to #1204. There do not seem to be a any releases between .21 and .33.
* Support Bazel builds on Apple silicon
* Add sha_mac_arm64 hash for 3.1.3
* Configure node_repositories in emscripten_deps.bzl
* Add mac arm64 to bazel workspace update script

* Makes provided bazel rules look up @emsdk workspace instead of local workspace
* Uses system-specific emscripten binaries instead of defaulting to linux
* Provides macros for loading emsdk dependencies (nodejs and emscripten binaries)
* Unhardcodes paths in bazel rules and .sh wrappers
* `update_bazel_workspace.sh` now updates `revisions.bzl`
* `emscripten_deps()` can be fed with specific emscripten version
* Adds external usage test
Addresses #650 and #696
This change comes with fairly major change to the bazel toolchain.
- Use pre-built cache that comes with emsdk
- Mark cache as readonly using FROZEN_CACHE
- Pass `--sysroot` to match upstream emscripten change
