  • Adds an EthdebugSchema header with the relevant part of the schema mapped to structs with corresponding to_json methods and validations
  • Skips the context for instructions with source locations that are not valid (ie, (-1, -1))
  • Adds source location info in evmasm assembly for assembleEOF
  • Refactors legacy assemble to use RAII-style instruction location gathering

Fixes the unoptimized part of #15978.
Fixes #15998.

I want to take a closer look at this, especially the Assembly.cpp part, but for now just a few small annoyances I found while doing a quick initial pass.

The output here is quite long and seems to have little to do with ethdebug itself (the ethdebug JSON gets stripped). Do we need it all? What's the point?

I think I just added it because there is the same test for non-eof. And looking at it now, I agree. There doesn't seem to be much value to keep it (or: them) around, especially with #16009 around the corner. I have removed this one.
