LOG: [lldb] include `LLVMTargetParser` in `LINK_COMPONENTS` (#145606)

## Purpose
Fix duplicate symbol definition errors when building LLDB `HostTests`
against a LLVM Windows DLL.

## Background 
When building LLDB `HostTests` against LLVM built as a Windows DLL,
compilation fails due to multiple duplicate symbol definition errors.
This is because symbols are both exported by the LLVM Windows DLL and
the `LLVMTargetParser` library.

## Overview
The issue is resolved by adding `LLVMTargetParser` (e.g. `TargetParser`)
to `LINK_COMPONENTS`, which adds it to `LLVM_LINK_COMPONENTS`, rather
than `LINK_LIBS`, which links directly against the library. This change
makes it behave correctly when linking against a static or dynamic LLVM.
