allow remote file argument for compiler directives

[maxandersen]

in tjake/Jlama#54 (review) there is a usecase to be able to specify filename to compiler directives.

i.e. -XX:CompilerDirectivesFile=%{https://raw.githubusercontent.com/tjake/Jlama/main/inlinerules.json}% but seems like we only do remote file arguments for arguments to script and explicitly javaagents argument - and only for the run/jar command; not the build.

Here we would need to do it for compiler flags.

@quintesse wdyt - should we just add handlefileargument to all the things or only do this explicit one flag as done with agents?

Not sure to be honest 😅
