Add DB utilties for SiPixelVCal

[mmusich]

PR description:

This PR adds few utilities to be able to inspect payloads of the type SiPixelVCal introduced in PR #29829.
It does:

• introduce a series of classes for the Pixel Payload Inspector to plot payloads of the type SiPixelVCal;
• adds amenities to dump,fetch, import the new DB format;
• improves the related unit-tests;
• in order to avoid replication of boiter-plate code a couple of new getter methods: SiPixelVCal::getAllSlopes() and SiPixelVCal::getAllOffsets() are added to the CondFormat.

Here is an example of plot that can be produced with the new code:
