Move blob/transaction gas calculations out of `.../vm/gas.py`

[SamWilsn]

The vm module should only contain stuff relevant to the EVM. Blob and tx fee calculations should be moved into a higher module.

A few other random gas constants that should be put somewhere better:

  	required to execute a transaction.

Noticed this issue while doing some related research work

I took a stab at it in the PR linked above. It's an initial draft, if it looks good I can keep working on it and do whatever it is required to complete it

Looking forward to any comments, ty
