chore(build): refactor build.sc and bump dependencies

[Emin017]

• Removed unused imports (scalafmt, os.Path, publish).
• Standardized rocket-chip module definitions under millbuild namespace.
• Updated defaultVersions to include sourcecode dependency.
• Modified millSourcePath assignments to use super.millSourcePath.
• Added mainargs and json4s-jackson as ivyDeps for rocket-chip.
• Updated moduleDeps to reference renamed rocket-chip object.
• Changed test module to use SbtTests instead of SbtModuleTests.
• Improved consistency in dependency declarations across modules.
• Bump mill from version 0.11.1 to 0.12.5

Thank you for your attention!
But I'm sorry that this is not merging before some critical checkpoints of our verification roadmap.

Is it because this projects are still using an old version of chisel? But I don't think the mill version will affect the verilog generation.

But I think it's understandable and I'm happy to wait for the necessary updates.

It seems jodersky/[email protected] doesn't support to download mill version 0.12.5 , I'll try to fix this.

We have several seperate teams and personnel working on different aspects of verification, and some environments and workspaces were designed to run offline. So at this point of time, it's might be not proper to introduce environmental jitters.

But still, we are very glad to have this kind support from you and your community!! 😄
