RFR: 8364037: Sort share includes: adlc, libadt, metaprogramming [v3]

[Francesco Andreuzzi]

> This PR sorts includes using test/hotspot/jtreg/sources/SortIncludes.java in:
> - hotspot/share/adlc 
> - hotspot/share/libadt
> - hotspot/share/metaprogramming
> 
> I noticed some missing includes in several header files in`adlc/`, which caused compilation success to be dependent on the order of include statements in `adlc.hpp`. I moved the include statements to `adlparse.hpp` and `forms.hpp`.
> 
> I'm also adding the directory to TestIncludesAreSorted.java.
> 
> Passes tier1 and GHA.
