TemplateTool&erp5_forge: resolve provision dependency by satisfied provider dependencies and version restricted

When a bt5 depends on a provision bt5 name, the resolver had only one
rule: pick the only candidate. With two or more candidates,
it will show "select one of the following business templates"

let's improve it by adding a new rule:

look at each candidate's own dependency_list and pick the candidate matchs version restricted and whose dependencies
are all installed or about to be installed.

When multiple matches, raise explicitly so the ambiguity is visible.
