patch 9.1.2065: GvimExt cannot be linked statically using MinGW

Problem:  When building GvimExt with MinGW, some DLLs are still linked
          even if STATIC_STDCPLUS=yes is set.
Solution: Following the Vim core, make some libraries explicitly
          statically linked.  The order of libraries is important, and
          gcc_eh must be placed before winpthread (Muraoka Taro)

closes: #19131
