feat(solo): adds support for Good Display GDEQ0426 eink 4.26 inch

Browse Source 
New solo env WioTrackerL1_GDEQ0426T82_companion_solo_dual: the Wio Tracker
L1 (Lite) with a Good Display GDEQ0426T82 (SSD1677) on the board's 24-pin
e-ink FPC. Build config only. Extends WioTrackerL1Eink with its own full
build_flags list so the stock panel's model and rotation never reach the
compiler.

RAM: the 800x480 framebuffer is 48 KB, so OFFLINE_QUEUE_SIZE is 32 and
MAX_CONTACTS 250 -- with the stock limits UiCore's heap allocations fail
at boot and it loops.

Tested on hardware: Wio Tracker L1 Lite + GDEQ0426T82.

; Solo build for Seeed Wio Tracker L1 (Lite) + Good Display GDEQ0426T82
; 4.26" 800x480 e-ink, plugged into the board's 24-pin e-ink FPC connector.
; Build config only -- no source changes. Extends WioTrackerL1Eink
; (variants/wio-tracker-l1-eink/platformio.ini) for its source files and
; libraries, but carries its own full build_flags list, so the stock panel's
; -D EINK_DISPLAY_MODEL / DISPLAY_ROTATION never reach the compiler too.
;
; - EINK_DISPLAY_MODEL GxEPD2 driver for this panel (GxEPD2 1.6.2+)
; - DISPLAY_ROTATION 0: the panel's native landscape
; - RAM: the 800x480 framebuffer is 48 KB (the stock 2.13" needs ~4 KB),
; and UiCore plus every screen is allocated from the heap at startup --
; a failed allocation there crashes into a boot loop. So:
; OFFLINE_QUEUE_SIZE 32 (stock e-ink: 128) frees ~17 KB
; MAX_CONTACTS 250 (stock: 350) frees ~18 KB
;
; Build: pio run -e WioTrackerL1_GDEQ0426T82_companion_solo_dual
