devcontainer: add Zephyr SDK install task to automations

Add installSdk task that:
- Reads SDK_VERSION from the fetched zephyr tree
- Downloads and installs the matching Zephyr SDK via west sdk install
- Patches SDK host tool ELF binaries to use the system dynamic linker
  (the SDK sysroot uses a hardcoded OE build path that doesn't exist
  on standard Ubuntu)
- Also adds patchelf, anytree, jsonschema to installDeps
