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

Jyri Sarha · Jyri Sarha · commit 90e463fc5d13 · 2026-01-12T01:16:04.000+02:00
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.
