The cache key of _get_bindings was not super efficient.
The result of _get_bindings is cached,
but its performance was altered by the cache
key which requires to fetch the user groups for each call to
_get_bindings.
Besides, as there is a lot of possible group
combination, this resulted in a lot of possible cache keys,
and therefore a lot of cached values.
This revision aims to make _get_bindings more efficient
by:
- do not use the groups in the cache keys (less cached values)
- filter out actions not available to the user groups after
retrieving them from the cache
- use has_group to do the above, which is itself cached as well,
and therefore do not need to fetch the user groups
at each call to get_bindings.
In addition, move get_bindings from `get_view`
to `get_views`. If there was 3 views asked by `get_views`
(let's say kanban, list, form)
`get_bindings` was being called 3 times, through `get_view`
with each time the same arguments and therefore the same result :-).
Moving it to `get_views` allows to call it only once for all view types
requested, and for the web client it doesn't change much,
as it always request the toolbar/get_bindings through `get_views` only.
In addition, add the lang to the cache of _get_bindings.
it was actually a bug not to put it: if you had 2 users
with the same group set, using 2 different languages,
the user accessing first the get_bindings would cache
the action names within his language, and then the second
user would see the action name within the language of the first user
:-).
Before
```py
In [1]: %time for i in range(1000): self.env['ir.actions.actions'].get_bindings('res.partner'); self.env.invalidate_all();
CPU times: user 790 ms, sys: 104 ms, total: 893 ms
Wall time: 1.7 s
```
After
```py
In [1]: %time for i in range(1000): self.env['ir.actions.actions'].get_bindings('res.partner'); self.env.invalidate_all();
CPU times: user 23.5 ms, sys: 9.12 ms, total: 32.7 ms
Wall time: 36.9 ms
