Nim: update to v2.0.0, adopt
https://github.com/void-linux/void-packages/pull/45597

Description:
#### Testing the changes
- I tested the changes in this PR: **YES**

#### Local build testing
- I built this PR locally for my native architecture, (x86_64 glibc)
- I built this PR locally for these architectures:
  - aarch64
  - armv6l
  - x86_64-musl

#### Notes

Other than version bumps, the only change is adding `git` as hostmakedepends. The new version of `koch` (Nim build script) clones some extra dependencies for bootstrapping the Nim `libffi`. See <https://github.com/nim-lang/Nim/commit/14bc3f32683c87f971bf23ae30d500dc89cdebb8>.

I'm not sure if I should find a way to patch/disable it instead, or if that is OK.
