ArmPkg: Remove Deprecated ArmPsciResetSystemLib

ArmPsciResetSystemLib has been deprecated since commit
b2c55e732888fd721f5235a820b1d1c45209992d in 2017. The
lib itself has not been meaningfully updated in 10 years.
This commit removes the library to complete the deprecation
process and remove confusion over which library to use for
resetting an ARM platform.
