Intel: platform: use Kconfig for IDC stack size

On Intel platforms, SOF_STACK_SIZE is only used to define the IDC worker
thread stack size. However, a Kconfig option, CONFIG_SOF_STACK_SIZE,
already exists. On some platforms, the IDC worker thread stack size was
hard-coded in memory.h, which appears to have been an oversight.

The default value of CONFIG_SOF_STACK_SIZE is 4096, but it is increased
to 8192 for the PTL board and in some overlays, such as the MTL DAX
overlay. Therefore, this change also increases the IDC worker thread
stack size for those configurations.
