    [FEAT] Add CMake namespace aliases for source dependency builds (#479)
    
    ## Summary
    Add namespace-qualified ALIAS targets (tvm_ffi::header, tvm_ffi::shared,
    tvm_ffi::static) that point to the in-tree build targets
    (tvm_ffi_header, tvm_ffi_shared, tvm_ffi_static).
    
    ## Problem
    When tvm-ffi is used as a source dependency, `tvm_ffi_configure_target`
    expects `tvm_ffi::header` / `tvm_ffi::shared` targets to exist. However,
    these are only created by the package config file
    (`cmake/tvm_ffi-config.cmake`), which is not included during source
    builds. Downstream projects using source dependencies cannot use these
    targets.
    
    ## Solution
    Create ALIAS targets in both:
    - Top-level `CMakeLists.txt` for `tvm_ffi::header`
    - `cmake/Utils/Library.cmake` for `tvm_ffi::static` and
    `tvm_ffi::shared` (created by `tvm_ffi_add_target_from_obj`)
    
    This ensures the namespace-qualified names are available in both source
    and package builds.
