Change "COMPANY_NAME" to "PACKAGER_NAME"

[thaJeztah]

follow-up to #3310

The COMPANY_NAME currently sets the "CompanyName" field in the metadata
of Windows binaries. Our intent of this field is this field to contain
information about the company/party that produced the binary.

Also from FileVersionInfo.CompanyName:

Gets the name of the company that produced the file

Based on the above, "PACKAGER_NAME" is a bit more generic, and clearer
on intent, and we may at some point re-use this same information to
propagate equivalent fields on other platforms (rpms, debs)

We should also have a look at the LegalTrademarks field; looks like we currently leave it empty, but perhaps would be good to (at some point) also set it.

It's a bit ambiguous though what should be in there (initially I thought that should contain something like "docker, the docker logo, and... are trademarks of docker. inc.", but the description from https://docs.microsoft.com/en-us/dotnet/api/system.diagnostics.fileversioninfo.legaltrademarks?view=net-6.0 describes it as:

The legal trademarks include the full text of all notices, legal symbols, and trademark numbers.

Which would potentially mean all NOTICE files of source we use, so we need to check what should be in that field.
