fix(windows/amf): Revert RC/HRD defaults; improve documentation & config parsing

[psyke83]

Description

• Revert RC and HRD defaults back to 'vbr_latency' and 'disabled' due to encoding artifacts or quality regressions noted on several cards.

• Document all new and existing AMF options in the docs and UI. Rearrange AMF options to better reflect importance (Usage is primary) and group by relatedness; group RC and HRD together, group all other quality-related sub options together.

• Various cleanups & fixes to AMF option parsing, including proper setting of defaults when invalid configuration is parsed.
