feat(autoupdate): Try decoding invalid hash value with base64 in format_hash

[AkariiinMKII]

Description

This PR moves base64 decoding process to format_hash function, which is formerly in find_hash_in_textfile and find_hash_in_headers, and add debug output before formatting.

It will make following effects:

• find_hash_in_rdf: Try decoding invalid hash value with base64.
• find_hash_in_textfile: Additionally try decoding invalid hash value found by file name with base64.
• find_hash_in_json: Try decoding invalid hash value with base64 (Aimed to solve issue [Feature] Decode base64 hash value fetched in json mode  #6271).
• find_hash_in_xml: Try decoding invalid hash value with base64.
• find_hash_in_headers: Skip decoding if fetched hash value is valid.

It should not affect valid hash value that matches the format.

Motivation and Context

Closes #6271
