base: Add a M5_PUBLIC and M5_LOCAL attribute macro
There are cases where we need to limit the symbol visibility to avoid
compilation errors. This is a problem for Python code that relies on
PyBind11 since recent versions enforce hidden symbols. As a
consequence, classes that have member variables from PyBind11 need to
be declared with the hidden attribute (or gem5 needs to be compiled
with -fvisibility=hidden).
