Quim Muntal 6f7b553c82 cmd/cgo: avoid exporting all symbols on windows buildmode=c-shared
Disable default symbol auto-export behaviour by marking exported
function with the __declspec(dllexport) attribute. Old behaviour can
still be used by setting -extldflags=-Wl,--export-all-symbols.

See https://sourceware.org/binutils/docs/ld/WIN32.html for more info.

This change cuts 50kb of a "hello world" dll.

Updates #6853
Fixes #30674
