[WebDriver BiDi] respect "WebDriver BiDi scripting is enabled"

[sadym-chromium]

Based on #11441. The bare minimal required changes.

• Enable scripting disabled emulation via WebDriver BiDi. Required for WebDriver BiDi command emulation.setScriptingEnabled.
• Allow bypassDisabledScripting to force-run scripts. Required for some automation scenarios like WebDriver BiDi command script.evaluate.

The following nuances are kept untouched and should be addressed later on as a part of Based on #11441:

• The "get the current value of the event handler" and "event handler IDL attribute" will return null when the JS is disabled.
• "8.1.6.6.2 HostEnqueueFinalizationRegistryCleanupJob(finalizationRegistry)" will NOT run when the JS is disabled. Meaning the FinalizationRegistry will not work even for scripts created with bypassDisabledScripting
  flag.
• "8.1.6.6.4 HostEnqueuePromiseJob(job, realm)" will NOT run when the JS is disabled. Meaning the FinalizationRegistry will not work even for scripts created with bypassDisabledScripting
  flag.
