Refactored the controller to read variables from the request

This ensures that the variable values used to dump the asset are the one
requested for this url instead of expecting that the value supplier is in
the same state than when generating the url for the asset.
This assumption is already an issue for the default supplier: the
symfony environment is likely to be the same, but the request locale is
based on matching _locale, not locale. So the controller will generally
use the en locale unless a listener changed it.
Added route requirements for the asset variables

This is needed to ensure the correct matching of routes. Otherwise, the
route for the combined asset /main.{locale}.js will be matched when accessing
the url for the leaf /main.en__1.js for instance, using the wrong value
for the variable.
It is also needed to avoid weird restrictions on the allowed values when
generating the route. The autogenerated requirement for the variable in
the combined url would forbid / and . (as the next delimiter char is a
dot), while the url for the leaf url would forbid / and _ for the last
variable. There is no reason to impose such weird restriction on possible
variable values.
On the other hand, the list of allowed values is known by the bundle (it
is required to allow dumping assets). So we can generate the proper
requirement to forbid other values in the url (which would generally break
the rendering by trying to access a non-existent file).
