libc/common: Refine check for xtensa _heap_sentry

Browse Source 
Not all xtensa targets define the top of usable RAM via the _heap_sentry
address; it looks like the list is limited to esp32, esp32s2, esp32s3 and
intel parts. The first three all define HAS_ESPRESSIF_HAL, so key the test
using that or SOC_FAMILY_INTEL_ADSP.
