Remove surelog libs out of own folder, use soversion

[timkpaine]

Parallel of chipsalliance/UHDM#1002

• install into lib instead of lib/surelog, python files moved to lib/surelog-python (open to other options, should probably move to a real python package)
• use SOVERSION so that lib/libsurelog.so is now a symlink, and we install a versioned lib/libsurelog.so..

I can take a look, though it seems unrelated to this PR. As part of my Mac PR on the yosys plugins, I've removed all the custom conda stuff so maybe this will be more reliable/easily maintainable in the nearish future.

@timkpaine Looks like this is the root cause of the failure of the plugin:
https://github.com/chipsalliance/Surelog/actions/runs/6059758147
The run immediately before that on main was still working

@alaindargelas pretty sure its this: chipsalliance/synlig@ec729d5

@timkpaine correct. So you can make this PR official.
