fix: ~7% smaller bundle size by not packing unneeded yarnpkg/nm subdeps

[ChALkeR]

Replace @yarnpkg/nm import with direct @yarnpkg/nm/hoist import and remove a large unused code subtree

Refs: yarnpkg/berry#6611

Two commits so that the first one can be tested individually if needed -- it produces no changes in the dist

Before: 9563553 bytes, after: 8920653 bytes for dist/pnpm.cjs

More reduction is possible (to ~7551098 bytes, ~21% total) by fixing other usused yarnpkg imports, but let's start with this one

Should this be backported to v9?

Is it safe?

@zkochan

1. tsconfig changes -- completely safe, it had zero effect on the generated bundle

2. Import change / code removal -- should be completely safe, all other code was unused & was auto-removed by changing imports (and the method actually imported was not changed & is isolated from all that removed code)

3. @yarnpkg/nm version bump 4.0.2 -> 4.0.5 -- unsure. That's a semver-patch release though?

   These two prs (and only them) touched the code used here:

   • fix(nm): Stop hoisting rounds only when nothing were hoisted yarnpkg/berry#6495
   • fix(nm): optimize hoisting by treating peer deps same as other deps yarnpkg/berry#6517
