Pull request overview
This PR increases the configured shared LL user-space heap size for the PTL overlay to enable running more user-space pipeline tests under the current build configuration (with virtual heap enabled).
Changes:
- Increase
CONFIG_SOF_ZEPHYR_SYS_USER_HEAP_SIZEto0x80000(512 KiB) in the PTL LL user-space overlay. - Add explanatory comments describing why the heap size is extended and what memory is being repurposed.

Bump the LL heap size of 0x8000 (512 KiB). This is current maximum with CONFIG_VIRTUAL_HEAP (enabled by default for PTL).
This is a shortterm solution to allow more test to be run with current build configuration. This is using the virtual heap pool intended for keyphrase buffer. Now this memory is instead used to run user-space pipelines.
