Subject: [PATCH] chore: add linux-arm.yml workflow for Linux ARM builds

This commit introduces a new GitHub Actions workflow file (linux-arm.yml) for
building and testing Servo on an ARM runner (ubuntu-24.04-arm). The workflow sets up
the environment, builds Servo using an ARM target, and runs unit tests and bencher
jobs when enabled. Note that WPT tests are omitted for ARM as specified.
