refactor!: replace packer.nvim plugin manager with lazy.nvim

[packer.nvim](https://github.com/wbthomason/packer.nvim)
has some anti-features and bugs that were a deal breaker for me:

- Bootstrapping is not straightforward
- Snapshots are fundamentally broken, i.e.
if I removed a plugin I tried to restore a snapshot packer would not work.
- Luarocks install doesn't work on macos
- Packer compilation step is annoying and sometimes makes config files out of sync
with the current setup, which makes debugging and plugin development awkward

[lazy.nvim](https://github.com/folke/lazy.nvim) doesn't have a compilation step,
doesn't require [impatient.nvim](https://github.com/lewis6991/impatient.nvim) for speeding up
modules initialization, has a straightforward bootstrap process and in general has a better design than
[packer.nvim](https://github.com/wbthomason/packer.nvim).
