Migrate sei-wasmd into sei-chain as mono repo

[masih]

Merge git commit history from sei-wasmd into sei-chain and update the replace directive in root of sei-chain to use relative path.

Note

The merged commits from sei-wasmd point to v0.3.9, consistent with the version bubbled up to sei-chain prior to this migration. Note that 4 commits from sei-wasmd are excluded, where 2 of which carry functional significance. Due to issues detected during the bubble up related to high gas usage the work here explicitly excluded those commits. A seprate set of PRs will re-introduce the excluded commits to isolate risk from mono-repo migration.
The PRs that need to be seprately bubbled up to sei-chain are:

• [SEI-9788] Add unit test CI and codecov coverage sei-wasmd#80
• Do not replace gas meter when creating synthetic events sei-wasmd#82
