Feat/more granular permissions check in create apitoken (#4072)

## About the changes
This PR enables or disables create API token button based on the
permissions.

**Note:** the button is only displayed if you have READ permissions on
some API token. This is a minor limitation as having CREATE permissions
should also grant READ permissions, but right now this is up to the user
to set up the custom role with the correct permissions

**Note 2:** Project-specific API tokens are also ruled by the
project-specific permission to create API tokens in a project (just
having the root permissions to create a client token or frontend token
does not grant access to create a project-specific API token). The
permissions to access the creation of a project-specific API token then
rely on the root permissions to allow the user to create either a client
token or a frontend token.
