  [cmake] Make ExecutionEngine/Orc/Shared depend on intrinsics_gen to fix modules build

The LLVM_ENABLE_MODULES builds currently randomly fail due depending on the
headers generated by the intrinsics_gen target, but the current dependency only model
the non-modules dependencies:

```
While building module 'LLVM_ExecutionEngine' imported from llvm-project/llvm/lib/ExecutionEngine/Orc/Shared/TargetProcessControlTypes.cpp:13:
While building module 'LLVM_intrinsic_gen' imported from llvm-project/llvm/include/llvm/ExecutionEngine/Orc/ThreadSafeModule.h:17:
In file included from <module-includes>:1:
In file included from llvm-project/llvm/include/llvm/IR/Argument.h:18:
llvm/include/llvm/IR/Attributes.h:75:14: fatal error: 'llvm/IR/Attributes.inc' file not found
    #include "llvm/IR/Attributes.inc"
             ^~~~~~~~~~~~~~~~~~~~~~~~
```

Depending on whether intrinsics_gen runs before compiling Orc/Shared files we either fail or include an outdated Attributes.inc
in module builds. The Clang modules require these additional dependencies as including/importing one module requires all
includes headers by that module to be parsable.
