Remove "Physical memory (RAM) usage limit" option on Linux

Browse source 
Memory working set limit is not effective on Linux at all. See [`getrlimit(2)`](https://man7.org/linux/man-pages/man2/getrlimit.2.html) → `RLIMIT_RSS`.
Introduced in #16874, disabled for macOS in #19805. This PR hides the option for Linux too.
Worth to mention that #19805 did not deliver the change for WebUI. So there is also a small fixup, I covered both cases.
Also removed pointless "This option is less effective on Linux" remark.

PR #22680.
