[esp32] Pin static loop task stack to internal DRAM

The static loop task TCB and stack added in #15659 had no explicit
section attribute, so under some sdkconfig combinations (notably
CONFIG_SPIRAM_ALLOW_BSS_SEG_EXTERNAL_MEMORY) the linker can place them
in PSRAM. That is unsafe when CONFIG_SPIRAM_XIP_FROM_PSRAM is also
enabled, because the running task's stack must stay reachable while the
flash cache is disabled (asserted by esp_task_stack_is_sane_cache_disabled).
DRAM_ATTR keeps both objects in internal DRAM regardless of those configs.
