Resolve issues breaking Swift Wasm builds for sql-kit (#190)

* fix: Resolve issues breaking wasm build in sql-kit. Needed to require a newer version of swift-nio that supports wasm, and needed to narrow scope from the broad NIO dependency to the true dependency of just NIOCore.

* fix: Don't require a bump in the minimum swift-nio version.

Those compiling for wasm will need to find their own version of nio that compiles to wasm. In the near future, most latest versions of nio will compile to wasm, so this shouldn't be an issue.

* refactor: Only elide the full NIO dependency if WASI is the target platform. Otherwise, leave exports and dependencies unchanged to minimize any disruption to downstream dependencies.

* chore: Update minimum required version of swift-nio to 2.84.0, which is a release containing the latest wasm compilation fixes.

* ci: Adds wasm build to CI.

* chore: Clean out backwards compatibility provisions for NIO implicit dependencies. Latest testing indicates this won't be breaking to scope down to just NIOCore.
