[Feature] add scene metadata field for original date (of production)

[echo6ix]

Is your feature request related to a problem? Please describe. Many scenes, including website releases and movie scene compilations, are re-releases not accurately reflecting the original date of production. This will reflect an inaccurate chronological representation of the scene, of the performers age during the scene, etc.

Describe the solution you'd like Similar to id3v2 and MusicBrainz tag metadata, add metadata fields for original release dates for scenes:

Metadata field	Description
originaldate	Original date of production (YYYY-MM-DD) of the earliest release
originaldate_url	Source URL for the original date

Additional context i would consider these advanced metadata fields that would not be commonly used. Hence, to minimize confusion or accidental usage, their input forms should not be displayed in the scene metadata editor by default. i propose displaying them when activated via the scene editor's hamburger menu > show advanced tags (which would just change the css display value from hidden to block, or something along these lines)

This was recently discussed on discord. Users are still expressing confusion about what the "date" field represents, particularly when using the "Date" filter to try sorting by creation date.

Splitting the "Date" field and filter into separate "production date" and "release date" fields might be wise, at least to give "Date" a better description.
