Additional partition scheme min_spiffs

[reaper7]

with minimal SPIFFS partition size for bigger apps and OTA support

useful for problems:
#1194
#1282
but leaving the OTA functionality available (unlike no_ota scheme)

addition for:
535a55d
75b08d5

P.S. is there a possibility to add partitions select for all available boards? (not only for esp32 dev board)

[me-no-dev]

yeah... to add partitions to all boards we should figure out either a board generator, or combine the boards and change the variant as a submenu. Boards are too many anyway and most are the same

Another problem is a hardcoded upload.maximum_size.
For large application we select partition scheme for "big apps",
partitions will be properly prepared but at the compilation end we still get exceeded size error,
because we compare compiled sketch size with hardcoded upload.maximum_size
but it should be compared with the right entry from selected partition.

^ This is a problem I'm running into. All sketches larger than 1310720 bytes report the following, regardless of partition size:
Sketch uses 1560446 bytes (119%) of program storage space. Maximum is 1310720 bytes.

Until this is fixed, you can still use the old method to Change partition size.
Works fine for me. Output from example sketch with Bluetooth and BLE included:

as @beegee-tokyo wrote, at this moment we have new partition file
and we have to make a change only in the boards.txt
