Subject: [PATCH] [caffe2] Remove cxx override to c++17 (#108687)

Summary: Allow the user to specify the cxx version to use when compiling. For applications that compile with C++20, we wish to also compile this library with C++20 to avoid subtle ODR violations with using different library standards.

Test Plan: Built the project successfully.
