Add 'watch-backend' (#12330)

Browse source 
* Add 'watch-backend'

This leverages `air` to watch the backend files and trigger `make
backend` automatically when they change. It seems to work rather well
together with `watch-frontend`.

Fixes: https://github.com/go-gitea/gitea/issues/12318

* rework docs to a new section for continuous build

See `make help` for all available `make` tasks. Also see [`.drone.yml`](https://github.com/go-gitea/gitea/blob/master/.drone.yml) to see how our continuous integration works.
The `build` target will execute both `frontend` and `backend` sub-targets. If the `bindata` tag is present, the frontend files will be compiled into the binary. It is recommended to leave out the tag when doing frontend development so that changes will be reflected.
See `make help` for all available `make` targets. Also see [`.drone.yml`](https://github.com/go-gitea/gitea/blob/master/.drone.yml) to see how our continuous integration works.
## Building continuously
Both the `frontend` and `backend` targets can be ran continuously when source files change:
````bash
# in your first terminal
make watch-backend
# in your second terminal
make watch-frontend
````
On macOS, watching all backend source files may hit the default open files limit which can be increased via `ulimit -n 12288` for the current shell or in your shell startup file for all future shells.

### Working on JS and CSS
For simple changes, edit files in `web_src`, run the build and start the server to test:
Either use the `watch-frontend` target mentioned above or just build once:
```bash
make build && ./gitea
```
`make build` runs both `make frontend` and `make backend` which can be run individually as well as long as the `bindata` tag is not used (which compiles frontend files into the binary).
For more involved changes use the `watch-frontend` task to continuously rebuild files when their sources change. The `bindata` tag must be absent. First, build and run the backend:
```bash
make backend && ./gitea
```
With the backend running, open another terminal and run:
```bash
make watch-frontend
```
Before committing, make sure the linters pass:
```bash
