script: Lazy init and reuse const BOOLEAN_ATTRIBUTES (#38423)

Browse source 
Follow up of  #38401.
- The constant String array was recreated for every invocation. Chromium
store this as a global const.
https://source.chromium.org/chromium/chromium/src/+/main:chrome/test/chromedriver/element_commands.cc;l=48-94?q=chrome%2Ftest%2Fchromedriver%2Felement_commands.cc
We now use static `LazyLock` to lazy init and avoid recreation.
- Clean up some comments

Testing: Just refactor.
