Computing the `cache_key` turned out to be a big factor during the lifespan of a `BaseModel.mapped` call and a lot of this time is spent computing the same `cache_key` over and over. These unnecessary computations can be easily reduced to a couple by moving the `cache_key` method on the environment (instead of the field) and by implementing a memo for that method. The rationale is that the `cache_key` of a field does not change for a given environment. The result of this patch is up to 50% faster `Field.__get__` which in turn means a GLOBAL gain in performance, especially for methods / functions that rely heavily on `__get__` such as `BaseModel.mapped`. closes odoo/odoo#42674 Signed-off-by: Adrian Torres (adt) <adt@odoo.com>
