Verilator expects `-std=c++14`

[goekce]

I stumbled upon the following error when following https://github.com/SpinalHDL/VexRiscv/tree/master?tab=readme-ov-file#murax-soc using Verilator 5.028:

$ make clean test
error: #error "Verilator requires a C++14 or newer compiler"

The following makefiles still use -std=c++11:

..VexRiscv $ grep -ri c++11
src/test/cpp/briey/makefile: ...
src/test/cpp/regression/makefile ...
src/test/cpp/murax/makefile ...

The simulation works when I remove -CFLAGS—std=c++11. If a maintainer confirms, I can create a PR.
