[Build] Reduce code size to allow for some bugfixes in limited builds

[tonhuisman]

Features:

• Another round of code optimizations, this time so we can fit in bug-fixes and improvements

Most reductions are from String and log statement optimizations, but also from deleting unneeded Device[] initializations.
Updates to .ino files.

• Round 1: ca. 1.7 .. 1.9kB reduction for ESP8266 and 2.2kB for ESP32 (MAX) ([P001]..[P053])
• Round 2: up to 800 more bytes reduction for ESP8266 and 1.2kB more for ESP32 (MAX) ([P054]..[P091])
• Round 3: up to 250 more bytes reduction for ESP8266 and 512 more bytes for ESP32 (MAX) ([P092]..[P110])
• Round 4: cleanup PLUGIN_DEVICE_ADD function (as suggested by TD-er) reduces most ESP8266 builds by 1..2kB, and ESP32 builds by up to 4kB
• Round 5: cleanup remaining .ino files ({P111]..[P176])
• Bugfix: AdaGFX_helper: Handling of arguments for [<taskname>#length."some text"] (and also textheight) would only accept a comma separator, but should also accept a period.

Total gain for the most challenging build ESP8266 Display: 3992 bytes, And an ESP32-S3 MAX build: 9788 bytes.

Further optimizations to other parts of plugin code are planned in the somewhat near future.

• More optimizations
