Prevent override SOLR field definitions with Config field definition

Beginning on "search_api_solr 8.x-3.0" a "buildFieldDefinitions()" in "src/SolrFieldManager" is using luke query to take field definitions and then applying on them (or adding) field definitions from Config Definition. In case when a field is on SOLR index as well on configuration that cause a field definitions is overriden by (new SolrFieldDefinition(['schema' => ''])";

We have a field added to index with "@SearchApiProcessor()" annotation, the field is implementing "ConfigurablePropertyInterface" which should allow us to set a configuration to the field from '/admin/config/search/search-api/index/{index_name}/fields'.
