Increase stack to 2048 (from 1024).

For UDB (on stm32H743) we use AXI SRAM, which has 512KB in total.
And UDB only uses approximately 145KB, including 1KB of main_task stack.
We hit the stack overflow check when adding several recent features, so
increase it by a large margin to avoid this going forward.
