Support enabling htmx.logAll via <meta> tags to capture early events

Currently, when `htmx.logAll` is called, it only starts logging events after HTMX has been initialized. This means that some initial events can be missed, especially in scenarios where HTMX is used with async/await code or other deferred setups.

The root issue seems to be that the `logger` is null until `htmx.logAll` is explicitly invoked, which happens too late to capture early-stage events.

Could we add support for enabling the logger earlier in the lifecycle, specifically via a ?

Let me know and if okay I'll work on that.
