Xenoblade X shader database

[ScanMountGoat]

This requires finding a shader decompiler that's easy to build and use as an external tool similar to Ryujinx.ShaderTools. xc3_shader will need additional tests to make sure that the GLSL syntax works with the existing analysis code.

• parse legacy shader metadata format
• add xc3_shader subcommand to disassemble all camdo shaders
• annotate database with resource names for better readability
• parse shader assembly
• convert shader assembly to graph
• add xc3_shader subcommand to create xcx.json from disassembled outputs

This tool is precompiled and should work in theory. https://github.com/decaf-emu/decaf-emu/blob/master/tools/gfd-tool/gfdtool.cpp

The assembly parser can use pest with a modified version of the original grammar.
