Clean up color scheme migration

...avoiding to have code in configmgr that knows about the details of the data
stored in the configuration.  (See the comments starting at
<https://gerrit.libreoffice.org/c/core/+/139690/9#message-44703a2529c07bf1b0202ed3a232aa661784b159>
"Migrating product name related color schemes between different versions" for
details.)

This reverts the dubious changes of 583ea856f2aa227bb04581c5bcdc3a402f5a184f
"Migrating product name related color schemes between different versions" in
configmgr and offapi.  (Also, this moves the computation of sMigratedProductName
in MigrationImpl::copyConfig, desktop/source/migration/migration.cxx, to a saner
location than in the middle of the "check if the shared
registrymodifications.xcu file exists" block where that
583ea856f2aa227bb04581c5bcdc3a402f5a184f had placed it.)

(cherry picked from commit: 7f04bb393f830a2983e3e26485bbe217c66006ff)
