Add user meta options to Display Conditions

[gerardreches]

Describe the Problem

Currently I cannot set display conditions based on the value of a custom user meta.

Propose a Solution

Add a "User Meta" option within the User group found in the first select field in the Display Conditions popup.

Additional Context

Currently we can set conditions by login status, role, and registration date. But that's not enough, we need total control to set any type of condition.
