Support of sanitize { "Address" } to C-language

In addition to https://github.com/premake/premake-core/pull/2027
Now sanitize { "Address" } works only for C++ language, but this flag may be applied to C language.
I think flag
```
		sanitize = {
			Address = "-fsanitize=address",
		},
```
shoul be moved from `cxxflags` table to `shared` table.
