feat: raw binary files handling in request body

[marcosadsj]

Description

Feature that implements the ability to add binary raw files in body request, that detects the content-type and ensures that large files will not crash or block the app.

I tried to follow the same pattern as the multipartform feature to maintain consistency in the code.

Resolves: #2700 #3718

Requirements:

• Select multiple raw files and choose which one is enabled.
• Auto detect content-type of files
• Load file asynchronously only in the pre-request moment to not crash app or block main UI
• Ability to abort request before the file is completely read
