emulators/ares: update to 146, unbundle dependencies

Release notes:
https://ares-emu.net/news/ares-v146-released

• The provided release archive doesn't contain a root directory anymore, so the port has to replace WRKSRC with NO_WRKSUBDIR=yes. Additionally use DIST_SUBDIR to prevent collision among multiple versions of the unversioned DISTFILES.

• This release builds the binaries bin/arm7tdmi and bin/m68000 only if one of the relevant cores is enabled. The port reflects this by removing TOOLS_IMPLIES and by adjusting PLIST_SUB and pkg-plist accordingly.

• The LaserActive system is added to the list of experimentally supported systems in pkg-descr. While there, reorder the list of supported systems in order to match the order on the project's homepage.

• Unbundle several dependencies which are available in ports.
