Build tags setup changed to:
* !nodeploy => withdeploy
* nodeploy => !withdeploy
Also move the deploy feature out into its own release archives.
See #12994 for the primary motivation for this change. But this also greatly reduces the number of dependencies in Hugo when you don't need this feature and cuts the binary size greatly.
Fixes#12994
This was broken in the config rewrite in Hugo 0.112.0.
The workaround is to be explicit about setting these flag values (even if just using the defaults), e.g.:
```
hugo deploy --invalidateCDN --maxDeletes 256
```
Fixes#11127
Primary motivation is documentation, but it will also hopefully simplify the code.
Also,
* Lower case the default output format names; this is in line with the custom ones (map keys) and how
it's treated all the places. This avoids doing `stringds.EqualFold` everywhere.
