Features add a globals per template rendering ( e.g. per http request)

[mardiros]

At the moment, while rendering an HTTP request, we can't have globals variable per request.

While rendering templates in framework such as FastAPI, or pyramid, there is a request
object that can be passed to the rendering engine in order to get some request
context, it can render url or access to the current session.

While rendering a template, in classic Jinja2, we can set them while fetching the template,
in a get_template call
for example.

Using JinjaX, I propose that we can pass them with a __globals as we can have other __params already.

I am not sur that the implementation is thread safe but if it works for css or js, it could works for those variable.

Fantastic! I hadn't realized Jinja could have independent globals per template. I would make some changes, such as updating the globals of cached templates in components.py instead of catalog.py, but I can do that after merging.

Thank you for taking the time to code this feature (and for your patience).

I this this is a good approach !
