Integrated support for Mill BSP Server

[ckipp01]

Is your feature request related to a problem? Please describe.
BSP is now a first class citizen in Mill. It'd be great if Metals had the ability to generate the BSP config necessary for discovery and then auto-connect.

I'll also be keeping track of stuff that I find which will be important for Mill to implement on their side to ensure a good experience for Metals users.

• [BSP] - Support for workspace/reload com-lihaoyi/mill#986
• [BSP] - Diagnostics not being cleared after successful compilation com-lihaoyi/mill#987
• [BSP] - Missing build/taskFinish com-lihaoyi/mill#988
• [BSP] - Incorrect Range in Diagnostic. com-lihaoyi/mill#989

Describe the solution you'd like
Much of the work that is being done in #2154 will make this much smoother to do. I don't expect it to be too difficult.

Describe alternatives you've considered
Manually connect after creating the BSP config.
