treewide: make the entire generated config lua based (#333)

* modules: switch to gerg's neovim-wrapper

* modules: use initViml instead of writing the file

* treewide: make the entire generated config lua based

* docs: remove mentions of configRC

* plugins/treesitter: remove vim.cmd hack

* treewide: move resolveDag to lib

* modules/wrapper(rc): fix typo

* treewide: migrate to pluginRC for correct DAG order

The "new" DAG order is as follows:
- (luaConfigPre)
- globalsScript
- basic
- theme
- pluginConfigs
- extraPluginConfigs
- mappings
- (luaConfigPost)

* plugins/theme: fix theme DAG place

* plugins/theme: fix fixed theme DAG place

* modules/wrapper(rc): add removed option module for configRC

* docs: add dag-entries chapter, add release note entry

* fix: formatting CI

* languages/nix: add missing `local`

* docs: fix page link

* docs: add mention of breaking changes at the start of the release notes

* plugins/neo-tree: convert to pluginRC

* modules/wrapper(rc): add back entryAnywhere

* modules/wrapper(rc): expose pluginRC

* apply raf patch
