cmake: add flags to only build the compiler

... and to use an external compiler

For example, this is how one only build the compiler:

```
cmake .. -DSLINT_BUILD_RUNTIME=OFF -DCMAKE_INSTALL_PREFIX=/tmp/slint_compiler
make install
```

And this only build the runtime
```
cmake .. -DSLINT_FEATURE_COMPILER=OFF -DCMAKE_INSTALL_PREFIX=/tmp/install_runtime
make install
```

And then this can be used in a project like so:
```
cmake .. -DCMAKE_PREFIX_PATH=/tmp/install_runtime/ -DSLINT_COMPILER=/tmp/install_compiler/bin/slint-compiler
```
