Add entry in packages_conan_package_reference when uploaded a new conan package file

What does this MR do and why?

Linked to global task #480355, next step after !167888 (merged)

We are in the process of converting the package_reference as string in conan package file to a reference to another table that contains the reference and some other metadata.

This MR, add an entry in packages_conan_package_reference when a new conan package file is uploaded, if the reference does not exist, and link it to the file.

Note: Reading the data is still done by the old field conan_package_reference, as data still need to be migrated for old package files. This will be done in a future MR.
