PrmPkg: Add initial PrmSsdtInstallDxe module

Adds a new module that installs a PRM SSDT.

Note: A library class would allow a high degree of flexibility for
platforms that choose:
  1. To not install a PRM SSDT at all (using a NULL library instance)
  2. To install a specific PRM SSDT implementation

However, it is implemented as a driver since build tools are not
linking ACPI tables to drivers from linked library classes.
