partition_table: Expanding the space under the bootloader

Browse Source 
Allows you to move the partition table, it gives more space for the bootloader.
Added a new utility - parttool.py. This utility can search for the offset and/or size of the partitions by name and type/subtype. Use for getting APP_OFFSET and PHY_DATA_OFFSET.
The linker(esp32.bootloader.ld) made changes that allow you to write a custom bootloader code more.
