Finalize OTA Requestor API

[selissia]

Problem

The platform and application OTARequestor API needs to be much more extensive than it currently is.

Proposed Solution

Collect, evaluate the already existing API proposals and if deemed viable add the corresponding declarations.

Several proposals are given here: #11605

src/app/clusters/ota-requestor/ota-downloader.h
// Platform calls this method upon the completion of ProcessBlock() processing
void virtual OnBlockProcessed(BlockActionType action);

In case if error occurs during the block processing, should there be some status which tells why the processing failed along with the action?

For this we'll need to dd "error" enum value for BlockActionType

public:
// Open file, find block of space in persistent memory, or allocate a buffer, etc.

Would it help if we have an option to resume the download?
