Don't do nested resize operations in TableResizeHelper

[iloveeclipse]

Avoids endless resize operations & UI hangs in case resize listener/handler code itself triggers some OS specific resize events.

Fixes #3676

@HeikoKlare : I can't reproduce on Linux, so it looks like it is Windows specific. Could you please check if you can reproduce?

I can't reproduce on Linux, so it looks like it is Windows specific. Could you please check if you can reproduce?

I tried different setups and inputs, but I was not able to reproduce the originally reported issue. Since the report mentions that the issue is sporadic, it seems not so easy to provoke that situation.
Since we quite some changes to control-sizing-related functionality because of the HiDPI functionality on Windows, I also checked if there might be anything involved here (which might have also been resolved recently), but I didn't find anything related.

Given the information we have from the error stack trace, the proposed solution seems fine to avoid a freeze. Since we don't know why the resize triggered itself repeatedly, there is a slight risk of a side effect/regression by the table potentially not reaching a "stable" resized state. But would still be better than running into a freeze.

Thanks Heiko.
