iwlwifi: trans: parse and store debug ini TLVs
The new debug ini TLVs can be either packed into firmware binary or written in external file. Support loading them from both. Store the data per apply point. Apply point is a point during driver runtime, where the TLV becomes active. For example, a trigger of hardware error may be configured to collect a subset of data pre-alive, as a opposed to HW error that occurs after alive.
