FreeRTOS.h configSTACK_DEPTH_TYPE inconsistent with default type

[feilipu]

Description
In #942 the default configuration value was inadvertently left set as uint16_t in FreeRTOS.h. Later updates to the merged PR omitted to update the configuration default to StackType_t.

It should be updated to StackType_t, to match the rest of the already merged PR #942.

Targets
All targets use FreeRTOS.h, where the default is incorrect.

Additional context
Some targets need to use the added default definition in portable.h from #942 to build, as they don't include FreeRTOS.h before using the definition. I think that this is probably bad, and is probably bugged too.

The duplicate default in portable.h should be removed, when the ports are repaired.

Hi @feilipu
Thanks for pointing the issue. We have merged the PR #987 with the necessary changes . We will look into the port issues you mentioned and address it in a later PR, if required.
