[jdk11u-dev] RFR: 8217527: jmod hash does not work if --hash-module does not include the target module [v2]

> I'd like to backport this fix because currently `jmod hash` command does not work on already created modules and this fixes that issue. This isn't intended behavior; nothing in Oracle documentation states this limitation, and moreover the command itself gives opaque response: there's no error message or non-zero exit, instead the command does nothing and no modules are changed after hashing.
> 
> The backport isn't clean because of conflicts in `HashesTest.java`. The conflicts are due to later commits being backported first; resolution was simple as all the jdk11u-dev master was kept. This change was ran on internal Amazon pipelines and passes jtreg tier1-4 + tck tests on the following platforms: linux x64, aarch64, x86, aarch32; macos x64, aarch64; windows x64, x86.
