topology2: Widget defaults for stack, lifetime, interim and shared memory

Jyri Sarha · lgirdwood · commit 662c72ccd1f5 · 2026-01-27T21:30:05.000Z
Add default values for stack, lifetime heap, interim heap, and shared
memory sizes for all widgets, e.g. module instances. These values were
tested with vpages branch and all cases that I tried worked with them.

Eventually each module should be added with more accurate values, based
on measurements.
