soc/intel/{common,apl,glk}: guard PM Timer option on SoCs w/o PM Timer
Apollo Lake and Gemini Lake do not have a hardware PM ACPI timer but
only uCode PM Timer emulation. Add a Kconfig `NO_PM_ACPI_TIMER` denoting
SoCs without PM Timer and make it mutually exclusive with the Kconfig
`USE_PM_ACPI_TIMER`.
This is partly redundant to `PM_ACPI_TIMER_OPTIONAL`, which will be
dropped in the follow-up change, though.
