chore(wasmer): add helpers.go file with helper functions

[qdm12]

Changes

• Split out (CGO related) helper functions from imports.go to lib/runtime/wasmer/helpers.go
• Move pointer size helper functions to lib/runtime/wasmer/helpers.go
• Change toWasmMemorySized to NOT take a size argument (unneeded)
• Clarify all comments for helper functions
• Update all error wrappings
• Review variable names
  • Use ptr instead of out for 32 bit pointers
  • Use pointerSize instead of span for 64 bit pointers size
  • Name return values
  • Other minor renamings such as res to result, enc to encodedResult
• Optimizations:
  • storageAppend: use slice capacity allocation, copy and remove unneeded appends
  • toKillStorageResultEnum: use copy instead of append
  • toWasmMemoryOptional: remove unneeded variable copy

LGTM, just a suggestion: since all the operations relies on the wasmer.InstanceContext could we rename the file from helpers.go to context.go or instance_context.go?

Good suggestion, although storageAppend isn't really about context, and I also sneaked in pointer size conversion functions in there, so helpers.go seems appropriate for now.

Looks like Deepsource doesn't like having two cgo files in the same package and fails compiling, I'll convert this back to draft and fix this later. Maybe split this in another subpackage for the sake of deepsource 🤔

FYI, I noticed this was in prep of a possible use of wazero, and thanks for thinking of us.

wazero just cut its first beta tag (v1.0.0-beta.1) and also opened a gophers slack #wazero channel for support, updates and conversation! Note: You may need an invite to join gophers.

We've also been working harder on our website for things people usually can't find https://wazero.io/languages/

Wish you well and hope to see you around.

Awesome @codefromthecrypt thanks for letting us know! We're probably a few months away from switching to wazero due to other priorities, but it's definitely something we would all like to jump to for sure!
