feat(policy-service): Policy Service Update [PM-22723] Add combineMasterPasswordPolicies method

[Patrick-Pimentel-Bitwarden]

🎟️ Tracking

https://bitwarden.atlassian.net/browse/PM-22723

📔 Objective

Add to the policy service api to allow for generating the master password policy options without a user id.

Note: the mergeMasterPasswordPolicyOptions will be more relevant in a later pr. I pulled this work out of https://github.com/bitwarden/clients/pull/14869 into this pr so it could unblock another developer.

Converting to draft because I think these changes will be abandoned in favor of a master password policy service api. This was discussed with @eliykat and will see a separate pr shortly.

Closing because I brought the changes into the main pr to be reviewed with the other ac changes. See https://github.com/bitwarden/clients/pull/15319
