build: limit inlining in every file of the debug build

Browse source 
At -Og GCC only caps inlining growth in units over large-unit-insns
(10000 instructions). Smaller files inline ArduinoJson's helpers into
every caller: moving the JSON parsing out of Somfy.cpp grew the image by
19 KB, past the 1.5 MB app partition. Treating every file as large keeps
inlining at the level the big files already had and frees 13 KB.
