Marco Casaroli bfb2cd5541 Documentation/esp32s3-devkit: Describe the kernel build configurations.
Describe kernel_oct and kernel_n8r2 next to the other configurations of this
board.

The entry for kernel_oct carries what a user needs and cannot guess:  a KERNEL
build is the only mode with fork() on this chip, the page pool is reached
through a scratch mapping rather than a permanent window, the ROMFS is linked
into the kernel image so a change to an application needs the whole
export-import-mkromfsimg-relink chain, how to confirm that the ROMFS is really
in the image, and that the shell needs the full path of a program.

The entry for kernel_n8r2 states its limit.  Each region of a process is 2
pages, ostest has 115 KiB of text against a 128 KiB text region, and a larger
program needs a module with more PSRAM.
