Move "static" keyword out from wxDEPRECATED() macros to placate icc.

Move "static" keyword out from wxDEPRECATED() macros to placate icc.

Intel compiler gives warnings if the static keyword is not at the beginning of
the declaration and this happened when using it inside wxDEPRECATED() and
related macros because the declaration started with __declspec(deprecated) or
__attribute__((deprecated)) instead.

To avoid this problem, simply move "static" outside the macro.

Closes #12932.
