fix(cli): rewrite 'doom sync'; deprecate 'doom build'
This changes 'doom sync' to be smarter about responding to changed
package recipes/pins, changes in Emacs version, or instances where the user
has copied a config to a new system.

In all these cases, the user would formerly have to know about a
specific combination of 'doom sync -u' and 'doom build' to ensure Doom
is in a good state. With this change, 'doom sync' handles all these
cases.

Also, 'doom build' is now deprecated (and 'doom sync' now has a
--rebuild option to mimic its old behavior).

Also also, sometimes, a package may silently fail when cloned (which
used to result in an empty repo). Now, if this is detected, cloning will
be re-attempted up to 3 times before aborting with much more visible
error.

Note: these are stopgap solutions, until v3 is finished.

"Synchronize your config with Doom Emacs.
This is the equivalent of running autoremove, install, autoloads, then
recompile. Run this whenever you:
1. Modify your `doom!' block,
2. Add or remove `package!' blocks to your config,
3. Add or remove autoloaded functions in module autoloaded files,
4. Update Doom outside of Doom (e.g. with git),
5. Move your Doom config (either $EMACSDIR or $DOOMDIR) to a new location.
6. When you up (or down) grade Emacs itself.
It will ensure that unneeded packages are removed, all needed packages are
installed, autoloads files are up-to-date and no byte-compiled files have gone
stale.
OPTIONS:
-j, --jobs
Defaults to the maximum number of threads (or 1, if your CPU's threadcount
can't be determined)."
