`--from-logfile` parsing breaks when semicolons appear in paths

### Problem

Running this command in verbose (`-vv`) mode:

```sh
PS C:\Users\laura> beet -vv import --from-logfile "F:/Music/BEETS_IMPORTER_LOG"
```

Led to this problem:

```
(error: malformed logfile F:/Music/BEETS_IMPORTER_LOG: Can't mix absolute and relative paths)
```
See #4937 for further detail - in summary the log file partser can't distinguish between `;` that occur inside paths and ones that separate paths.

### Setup

* OS: Windows 11
* Python version: 3.10
* beets version: 1.6.1
* Turning off plugins made problem go away (yes/no): no

My configuration (output of `beet config`) is:

```yaml

Trace the `beet import --from-logfile` entry point and its logfile path parser first. Reproduce the issue with a path containing semicolons, then add regression coverage and verify that semicolons inside paths are preserved while separator semicolons still split paths.
