ci(e2e): run end-to-end tests on macOS and Windows too

Previously, end-to-end tests only ran on Ubuntu. This adds macOS
and Windows to the matrix, with fail-fast so a failure on one
platform cancels the others early.

Node 14 is skipped on macOS since it's unavailable on ARM runners.
Windows needs the MSVC toolchain for the native fuzzer addon build.
