Add offset-based pagination to list personal/group/project/impersonation tokens
# Background
The list of personal/group/project/impersonation tokens can be very large.
For example in production the user `gitlab-qa` (1614863) has 69366:
```
select count(id) FROM "personal_access_tokens" WHERE user_id = 1614863;
count
-------
69366
(1 row)
```
According to [this Sentry report](https://sentry.gitlab.net/gitlab/gitlabcom/issues/3313240/?query=user%3A%22username%3Agitlab-qa%22) the following query can take longer than 15000ms and cause a timeout:
```
SELECT "personal_access_tokens".* FROM "personal_access_tokens" WHERE "personal_access_tokens"."user_id" = 1614863 AND "personal_access_tokens"."impersonation" = FALSE AND (revoked = false AND (expires_at >= CURRENT_DATE OR expires_at IS NULL)) ORDER BY "personal_access_tokens"."expires_at" ASC;
Time: 1067.024 ms (00:01.067)
```
I suggest we change that above query for a offset-based query:
```
SELECT "personal_access_tokens".* FROM "personal_access_tokens" WHERE "personal_access_tokens"."user_id" = 1614863 AND "personal_access_tokens"."impersonation" = FALSE AND (revoked = false AND (expires_at >= CURRENT_DATE OR expires_at IS NULL)) ORDER BY "personal_access_tokens"."expires_at" ASC LIMIT 100 OFFSET 0;
Time: 766.373 ms
```
