fix(l2): WiFi fails to start or join - big statics and task stacks to PSRAM

Browse Source 
WiFi starts and joins on internal RAM: ~42 KB the first time, ~25 KB after,
more for WPA. Free internal RAM had shrunk to ~20 KB after opening the map
(the tile decoder's 12 KB stack, the 32 KB I-cache, the DMA draw buffers,
UI statics), so a scan failed at once (esp_wifi_init: no memory) and a join
during a tile download timed out (AUTH_EXPIRE).

- ESP-IDF: CONFIG_SPIRAM_ALLOW_BSS_SEG_EXTERNAL_MEMORY, and the esp_timer
  task stack 8 -> 4 KB (it uses ~0.4 KB). Rebuild the framework libs:
  pio run -e Wio_Tracker_L2_idf_libs.
- PSRAM_BSS (EXT_RAM_BSS_ATTR) on the UI's big statics: QR codes, map
  state, charts, lists. .dram0.bss 115 -> 66 KB.
- The tile decoder's and fetcher's task stacks in PSRAM.

Free internal RAM, idle: 48 -> 105 KB; WiFi up: 57 KB, 29 KB at the
lowest while downloading tiles.
