In general the strategy is to consider all osgi.ee requirements of a resource and parse their filter.
For the case of a simple filter like '(&(osgi.ee=JavaSE)(version=17)', probably the majority of cases, a fast-path is provided where the filter is just looked up in a map.
Otherwise each registered execution-environment is matched against the filter and the list of matching EEs is returned.
The new method is intended to support the migration from the Equinox resolver to the OSGi Resources/Wiring API.
It is required for #1302 and #1318
