[PATCH 0/1] MR1827: ntdll: Add basic support for application configuration files

[Johnny Cai (＠jaihysc)]

Some applications have a `<name>.exe.config` file with the element
`<probing>` to specify additional directories to search for assemblies. As
it is not handled in wine, these applications fail to load.

To keep this commit simple, it only supports probing. The other parts of
the application configuration file are unimplemented.
