Retrieve all user repo perms with a single API call (#3211)

This pull request addresses the issue https://github.com/woodpecker-ci/woodpecker/issues/3210.

Ideally, the Bitbucket API should include repository permissions when
utilizing the 'get all repositories' endpoint. However, as it currently
does not provide this information, a viable solution is to fetch all
permissions for every repository and then employ a dictionary to
associate each repository with its respective permissions.

Without implementing this fix, logging in becomes problematic for users
with access to a substantial number of repositories (300+), as the
process takes over 2 minutes to complete.
