PRs apache#14913 and apache#14914 made analogous changes to `MakePackedAPI` and `MakeUnpackedAPI` to handle subroutine calls. Both PRs introduced the same symbol, `tvm::tir::SubroutineCallRewriter`, a local utility to update internal calls to a modified function. While each PR passed CI individually, and was therefore able to merge, having both changes caused a duplicate symbol. This commit updates `MakePackedAPI` and `MakeUnpackedAPI` to place their local utilities into anonymous namespaces, avoiding the conflict.
Previously, calling a packed func that returns void would result in an error being raised from `tir::APIType`, as there is no runtime representation of a void type. This commit updates `CodeGenCPU::MakeCallPackedLowered` to only read the return value and type fo a `PackedFunc` when the TIR return type is non-void.

Previously, calling a packed func that returns void would result in an error being raised from
tir::APIType, as there is no runtime representation of a void type. This commit updatesCodeGenCPU::MakeCallPackedLoweredto only read the return value and type of aPackedFuncwhen the TIR return type is non-void.
