Add new call to not break existing code.

I ran into a build failure trying to use Zephyr's MCUmgr. It was a
missing symbol at link time, and since I am using C++, I looked to see
if it was a name mangling issue. The mcuboot.h header file was missing
`extern "C"` guards, which was the root cause of the issue.
This commit adds C++ support to mcuboot.h by adding in `extern "C"`
guards. I validated this change by building and running my DFU
application with MCUmgr successfully.

Consistently place C++ use of extern "C" after all include directives,
within the negative branch of _ASMLANGUAGE if used.
Background from issue #17997:
Declarations that use C linkage should be placed within extern "C"
so the language linkage is correct when the header is included by
a C++ compiler.
Similarly #include directives should be outside the extern "C" to
ensure the language-specific default linkage is applied to any
declarations provided by the included header.

move flash_map.h to storage/flash_map.h and
create a shim for backward-compatibility.
No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

Patch adds option for progressive erase of firmware image.
When using this, flash is erased as necessary when receiving
new firmware, instead of erasing the whole image slot at once.
This is useful on some hardware (like nRF52840) that has
long erase times, to prevent long wait times at the beginning
of the DFU process.

This function conflicts with a function of the same name in mcuboot.
This happens when building USB DFU support into mcuboot.
DFU over USB uses image manager and mcuboot internals to manage images
downloaded to the device.

Patch introduces flash_map subsystem to operate on flash
image instead of direct operation using flash_driver API.
Changes allows to support operation on the image in any flash
device.
flash_map was not available when this subsystem was introduced.

Duplicate code to query was mistakenly added in commit
2ad7ccdb2d. This code is redundant; the
existing `boot_read_bank_header()` function can read the version from
both image banks.

This is an accessor function for the MCUboot image header of an image
bank. The interface may seem a little cumbersome, but it is
future-proof against MCUboot feature and incompatible header version
changes.

Applications chainloaded by MCUboot may want to change their behavior
based on whether or not they are confirmed.
Here are some examples:
- performing a built-in self test (BIST) if the image is not yet
confirmed, and marking it OK if it passes (this enables reverting
to an older working image if the BIST fails, and allows future
resets to skip the BIST if it passes to improve boot time)
- interacting with persistent metadata related to image state on
other flash partitions during test upgrades (these are required in
cases when the update source provides runtime metadata, such as
monotonic counters, related to an upgrade attempt which must be
used to report results)
To enable these use cases, add boot_is_img_confirmed(), which reads
the "image OK" field for the current firmware image and returns true
if and only if it is set.
