IntelLLVM: Avoid unnecessary -Qstd=c++11 flag on Windows

The IntelLLVM compiler, for compatibility with MSVC on Windows, always runs with support for at least C++14. The -Qstd=c++11 flag just causes a warning that it is unused.

Fixes: #24316 (closed)
Backport: release

changed milestone to %3.25.2

added comp:intel-llvm os:windows workflow:in-review labels

assigned to @brad.king

Warnings:

• Eligible for the 3.25.x branch.

The warnings do not need to be fixed, but it is recommended to do so.
