feat: Put the debug/release build version into the info (#7034)

The info will look like:

```
debug_assertions=On - DO NOT RELEASE THIS BUILD
```
or:
```
debug_assertions=Off
```

I tested that this actually works when compiling on Android.

The deltachat_core_version line in the info will look like:

```
deltachat_core_version=v2.5.0 [debug build]
```
or:
```
deltachat_core_version=v2.5.0 [release build]
```
