feat(gpu): enable multi-bit test to the pattern dp ks ms

[guillermo-oyarzun]

First PR to enable multi-bit tests, the tricky part is that our pbs must have an option to receive an input already modulus switched. This affects only to the keybundle, however to keep the changes minimal the input of the keybundle will contain the original input array at the start of the array and the second part of the array contains the modulus switched values.
This order is needed cause the pbs needs to read the input body untouched (other ways to change it would imply also to change the blind rotation).

Check-list:

• Tests for the changes have been added (for bug fixes / features)
• Docs have been added / updated (for bug fixes / features)
• Relevant issues are marked as resolved/closed, related issues are linked in the description
• Check for breaking changes (including serialization changes) and add them to commit message following the conventional commit specification
