Add hexagonrpc service to xiaomi-elish

[amazingfate]

Description

After updating to kernel 6.11, slpi node of sm8250 will crash, and a userspace service hexagonrpc has to run to avoid that: https://github.com/linux-msm/hexagonrpc
This package is only packaged in my ppa qcom-mainline for noble, so only install and enable the service for noble.

I also remove pd-mapper and tqftp service since they are useless now, pd-mapper is in kernel.
