feat: add WASM host functions

[mvadari]

High Level Overview of Change

This PR adds all the WAMR integration code and the host functions specified in XLS-102. It also adds tests for all of this.

Note for reviewers: 10k lines of this PR are just WASM-compiled test fixtures, and another 4k lines are WASM test fixture source code. So while this PR is still quite large, it's not as large as it seems on the surface.

Context of Change

This PR depends on #5790

It is part of an effort to split up #5600 into smaller, more managable-to-review PRs.

XLS-102: XRPLF/XRPL-Standards#303
