This commit tries to improve the interactions involving unmounted
components, or components mounted in an htmelement which is detached
from the main DOM, and rendering actions.
The main example is mounting a component in detached div, to prepare all
children. If we just mount the component, it will work as expected: the
full component tree is rendered in memory, and ready to be really
mounted at the desired target.
However, if before doing that, we update the component and call render
on it (for example, with a change in an observed state), then this
rendering will be ignored, and therefore, the full subcomponent tree is
not uptodate.
This commit will also solve another issue in the compatibility layer in
odoo: in the form renderer, we mount components with the adapter in a
div, which is not yet attached to the DOM. We then manually call the
mounted hook when on_attach_callback is called. This means that before
this commit, any change to the components between the initial rendering
and the call to mounted will be ignored.
As a bonus, this commit has the effect of bringing closer the semantics
of render and mount operations, which is certainly good.

In most cases, we just want Component<any, Env>. But since it was so
annoying to have always the type Env, we actually used
Component<any,any> everywhere.
With this commit, the generic types have a default (and their order is
swapped), so we can simply use Component in most cases, and
Component<Props> when we want to type the props.
This commit is a significant refactoring of the internal of QWeb. It
simplifies the way variables/scoping and slots interact together. The
main idea is that we use a simple scope object instead of a
context/var/scope object.
This commit also implement the actual correct QWeb semantic for the
t-call directive with a sub body. Before, we simply extracted the
variables from the body and injected them at the top of the sub
template. We now simply compile the body before the sub template.
This is a joint work with Lucas (lpe).
