9d6c3632e8 bootloader: Fix regression burning efuses late in boot process
APB clock get functions not included in iram_loader_seg, meaning
could be overwritten by app depending on app IRAM size and linker
layout.

Regression in dd5190868a

Closes https://github.com/espressif/esp-idf/issues/5456

4a987dacca bootloader: keep bootloader_common code to retention region
It is possible to utilize some of the routines related to otadata
partition validation, after firmware image is downloaded to RAM. Hence
these routines should be part of app cpu cache, so that they do not
get overwritten by firmware.

5551b3f616 bootloader: move iram_seg 1k up to have better looking idf_monitor output
When 2nd stage bootloader loads the ROM bootloader, it prints a
message similar to "entry 0x40080xxx", which idf_monitor decodes
(using application ELF file) as one of the reset vectors (xxx is <
400h). This moves the iram_seg of bootloader 1k up to prevent overlap
of bootloader .text and application vectors, making the output look
nicer. There is still a chance that the entry point decodes as some
symbol in application ELF file, but at least it won't have
"Exception" in its name.

3e0ac4db79 partition_table: Expanding the space under the bootloader
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.

d664e32394 build system: Use component.mk for all components, refactor bootloader build
For config-only components, component.mk should now contain "COMPONENT_CONFIG_ONLY := 1"

Also refactored some of the generation of linker paths, library list. This required cleaning up the way the bootloader
project works, it's now mostly independent from the parent.
