[RTL] actctx.c: Reduce diff to wine

Browse source 
The changes are:
- Do not allocate an additional WCHAR for the terminating UNICODE_NULL, since we already have that accounted for by sizeof(manifest_dirW)
- Use strcpyW intead of memcpy / strlenW, which does the same thing
- Add a define for user_shared_data
