zephyr: Add MCBOOT_ERASE_PROGRESSIVELY config option 



The commit adds generalized MCBOOT_ERASE_PROGRESSIVELY options
that can be used to enable progressive erase of flash in
boot_serial DFU code.
The progressive erase is used to erase flash pages as image
update fragments come, instead of erasing the whole needed
image at the beginning.

/*

 * The option enables code, currently in boot_serial, that attempts

 * to erase flash progressively, as update fragments are received,

 * instead of erasing whole image size of flash area after receiving

 * first frame.

 * Enabling this options prevents stalling the beginning of transfer

 * for the time needed to erase large chunk of flash.

/*

 * Enabling this option uses newer flash map APIs. This saves RAM and

 * avoids deprecated API usage.
