[llvm] [lllvm] add Passes to LLVM_LINK_COMPONENTS for LLVMMCATests (PR #145617)

[Andrew Rogers via llvm-commits]

https://github.com/andrurogerz created https://github.com/llvm/llvm-project/pull/145617

## Purpose
Add `Passes` to `LLVM_LINK_COMPONENTS` for `LLVMMCATests` so that it links properly when LLVM is built as a Windows DLL. 

## Background
`LLVPasses` appears to be a missing dependency from `LLVMMCATests`, but when LLVM is built statically it picks-up the required `LLVMPasses` symbols from a transitive dependency (presumably). When LLVM is built as a Windows DLL, `LLVMMCATests` fails to link 4 symbols from `LLVMPasses` without this change:
```
