M3-5873: Build `api-v4` and `validation` with `tsup` with backwards compatibility

[bnussman]

✨ Description

• Use tsup for building @linode/api-v4 and @linode/validation

📝 Details

• Deprecates yarn up in favor of yarn dev
• Runs a dev server for @linode/validation so it rebuilds automatically when you are using yarn dev / yarn up
• Changes any src/ prefixed imports in @linode/api-v4 and @linode/validation to be relative path imports (../)
  • We should do this to keeps those packages simple. Aliases can causes extra complexity and is not beneficial in small packages like ours.
• Configure Cloud Manger's jest to use @linode/api-v4 and @linode/validation's srcinstead of lib.
  • We do this because jest was having trouble resolving exports because of its lackluster esm or exports support.
• Type generation is handled by tsc
• Use incremental tsc compilation for @linode/api-v4 and @linode/validation for faster typechecking
• We are going to publish esm, commonjs, and iife as 3 bundled formats
  • This results in 3 respective index.jss for each format (excluding type files)
  • Cloud Manager consumes esm
  • Jest will consume commonjs
  • Dependencies are only bundled into the index.js file for the iife format so it is suitable for web use

🧪 How to test

• Test all of Cloud Manager, @linode/api-v4, and @linode/validation
