Media: file details screen labeled as "space", file detail titles are not read if they have content, copy button not labeled as a button

[designsimply]

Steps to reproduce:

1. Go to Settings > Accessibility > TalkBack > "Use service" or use the Volume key shortcut.
2. In the WordPress app, go to My Site > Media.
3. Open the global context menu by swiping down then right and double tap "Read from top".

Result: (1m8s)

• On the main media grid, the instruction read aloud for a thumbnail says "double tap to activate, double tap and hold to long-press" but double tapping and holding to long-press does nothing.
• The first focusable item on screen is read as "space".
• Field titles under File Details are not read aloud if they contain content.
• "Copy" button under URL is not labeled as a button.

^{Tested with WPAndroid 13.8-rc-1 on Pixel 3 Android 10.}
