QuantumESPRESSO: Let internal EasyBlock not create a log file

[Thyre]

This fixes the increased disk usage when running the EasyConfig test suite as log files would stay open.
See easybuilders/easybuild-easyconfigs#21841 for more information.

Requires:

• EasyBlock: Allow to pass logfile from other EasyBlock easybuild-framework#4707

Fixes:

• test: Test suite doesn't remove log files for QuantumESPRESSO (nested EasyBlocks?) easybuild-easyconfigs#21841

---

Old Notes:

• During the EasyConfig test suite, some log files will be left over until the suite has finished. However, these files are now only ~1.1KB in size instead of steadily increasing in size.
• It's hard to test the changes in the CI.
• We need to check if these changes affect normal installation logs. Until then, marked as draft.

[Thyre]

Logs of normal build seem to be still working.
This is more or less a quick fix.

My idea for a more robust fix would be:

If we change the EasyBlock in framework to optionally accept a logger and only create a new one if one was not passed, we could pass in the logger from Bundle and QuantumESPRESSO to the inner EasyBlocks. This logger can then be closed with the normal close_log call.
This should also fix the leftover files in this PR. If we also want to make sure that this passed logger is not closed accidentally in the inner EasyBlock (which I would prefer), handling QuantumESPRESSO might get a bit more complicated due to the way the EasyBlock is written (basically replacing itself via __getattribute__). This can also be solved, but I have no good solution for that yet.

I will take a look and update this PR accordingly.

[Thyre]

CI fails as expected, due to changes in framework.

[Thyre]

Found issues with the implementation in framework. Changed the implementation and will try again.

[Thyre]

New changes in framework work together with this PR. The EasyConfig test suite fails due to GROMACS, but this is not related to this PR. Will leave this as Draft until the Bundle PR, initially introduced in #3472, is also ready and I'm sure that everything works for sure.
