fix(cmake): ensure D is automounted when using toolchain

[ReenigneArcher]

When using the toolchain file, the "D" drive is not automounted as it is when using the Makefile options. This PR fixes that using the same conditions as the Makefile option.

Otherwise you must add extra bits to the code to automount, such as https://github.com/abaire/nxdk_pgraph_tests/blob/4b7934e6d612a6d17f9ec229a2d72601a5caefc4/src/main.cpp#L118-L122

This was discussed on the discord server here: https://discord.com/channels/428359196719972353/428399682239332354/1296626606688833617

It may be better to use a cmake "option" with the value set to ON by default, and OFF when it desired to disable. This would be more standard for CMake, just let me know which way is preferred.

Edit: converted to draft as during my first test I had not cleared the cmake cache, thus the toolchain was not fully reloaded. Need to fix some things.

I will close this, as I don't know how to fix this using the toolchain by itself, but adding set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -include:_automount_d_drive") to the project's main cmake file seems to work fine.

It requires some other configuration as well, e.g. https://github.com/abaire/nxdk_pgraph_tests/blob/4b7934e6d612a6d17f9ec229a2d72601a5caefc4/CMakeLists.txt#L22
