fix: fix copy_shaders not working with auto-deploy

[FlayaN]

2 fixes:

• To fix the duplicate rule error:
  • This is caused by get_filename_component(TARGET_DIR ${DEPLOY_TARGET} NAME) not being unique (only taking the last foldername as the name of the .stamp file. This is why I had the MD5 in the previous version)
  • example:
    C:/Program Files (x86)/Steam/steamapps/common/Skyrim Special Edition/Data
C:/Modding/SkyrimVR/DebugModding/Data
    Both of these will end up with shader_timestamps/Data_timestamp.stamp as their name, causes duplicate rule
• Fix AIO folder not being generated
  • Added back copy into the AIO folder in build (Not sure why you removed this? Maybe this was not meant to be fixed like this, please let me know if I misunderstood your change to aio folder logic)
