CRM install query count can vary from one execution to another, leading
to difficulties when analysing performances evolution.
The main reason for this is that some compute methods were called in
different order. Even if compute order shouldn't have any effect on the
final result, making it well defined will help finding other causes of
non-determinism.
The initial observation was that sorting Environment.fields_to_compute
leads to a fixed number of query when installing crm.
The main cause of non-determinisim is the usage of `set` impacting
Field.compute_value and BaseModel._modified_triggers.
Transforming all these `set` to `OrderedSet` solves the problem.
The query count is now deterministic when installing a database from
scratch, but not when updating a database with -i crm.
OrderedSet is also slightly optimised by using a dict instead of an
