JDK 20 - Drop support for -source/-target/–release 7 from javac

JEP 182 (Policy for Retiring javac -source and -target Options) describes a policy to remove at a regular pace, from the javac compiler, support for obsolete versions. This is required to reduce compiler maintenance costs. JEP 182 still needs to be updated to reflect the 6-month release cadence but in that spirit and given that JDK 7 was released in July 2011, i.e. over a decade ago, support for -source/-target/--release 7 is dropped in JDK 20. All other supported values remain as such in JDK 20, 8 through 20 inclusive.
