Added a new structure esp_app_desc_t. It has info about firmware:
version, secure_version, project_name, time/date build and IDF version.
Added the ability to add a custom structure with a description of the firmware.
The esp_app_desc_t is located in fixed place in start of ROM secotor. It is located after structures esp_image_header_t and esp_image_segment_header_t.
app_version is filed from PROJECT_VER variable (if set in custom make file) or PROJECT_PATH/version.txt or git repo (git describe).
Add API to get app_desc from partition.
in the include file esp_ota_ops.h "esp_partition.h" is included.
This is from spi_flash so component that requires app_update also will need that
this fixes this error:
In file included from ../components/esp32-homie/ota.c:11:0:
/esp-idf/components/app_update/include/esp_ota_ops.h:22:27: fatal error: esp_partition.h: No such file or directory

* Philosophical: "explicit is better than implicit".
* Practical: Allows useful errors if invalid directories given in components as the defaults aren't
always used. Also trims the -I path from a number of components that have no actual include
directory.
* Simplifies knowing which components will be header-only and which won't
