tools: Rename the flash size detection kconfig option

Browse Source 
9c46c98b4c have changed the default value
of ESPTOOLPY_FLASHSIZE_DETECT. As the side effect, existing
projects (having the option still enabled) started to discard the SHA256 digest.

Rename the ESPTOOLPY_FLASHSIZE_DETECT option so existing projects would
have the value disabled by default.

Closes https://github.com/espressif/esp-idf/issues/9148

-------
The CONFIG_ESPTOOLPY_FLASHSIZE_DETECT option has been renamed to :ref:`CONFIG_ESPTOOLPY_HEADER_FLASHSIZE_UPDATE` and it is disabled by default. New and existing projects migrated to ESP-IDF v5.0 will have to set :ref:`CONFIG_ESPTOOLPY_FLASHSIZE`. If this is not possible because the flash size is not known at build time then :ref:`CONFIG_ESPTOOLPY_HEADER_FLASHSIZE_UPDATE` can be enabled but this will have the consequence of not appending a SHA256 digest after the image in order that the binary header could be updated with the flash size during flashing without invalidating the digest.
