zig rc: Fix include directory detection when cross-compiling from certain host archs (#24288)

* resinator: Only preprocess when the input is an .rc file

* resinator: Fix include directory detection when cross-compiling from certain host archs

Previously, resinator would use the host arch as the target arch when looking for windows-gnu include directories. However, Zig only thinks it can provide a libc for targets specified in the `std.zig.target.available_libcs` array, which only includes a few for windows-gnu. Therefore, when cross-compiling from a host architecture that doesn't have a windows-gnu target in the available_libcs list, resinator would fail to detect the MinGW include directories.

Now, the custom option `/:target` is passed to `zig rc` which is intended for the COFF object file target, but can be re-used for the include directory target as well. For the include directory target, resinator will convert the MachineType to the relevant arch, or fail if there is no  equivalent arch/no support for detecting the includes for the MachineType (currently 64-bit Itanium and EBC).

Fixes the `windows_resources` standalone test failing when the host is, for example, `riscv64-linux`.
