heap: Fix compilation error when CONFIG_SPIRAM is set on esp32s3 target

When CONFIG_SPIRAM is set, the TLSF_MAX_POOL_SIZE is set to SOC_EXTRAM_DATA_SIZE
which caused the TLSF_MAX_POOL_SIZE to be bigger than 16MB.

This commit fixes the issue by adding an extra else if case to cover this configuration.
