feat: Replace rc-scrollbars in favor of overlayscrollbars

[dougfabris]

Proposed changes (including videos or screenshots)

Our current custom scrollbars doesn't have support to RTL. So this PR aims to replace the usage of rc-scrollbars in favor of overlayScrollbars which does support. So doing it we'll be able to fix some a11y when using RTL languages

TO-DO

• Remove rc-scrollbars
• Remove rc-scrollbars CSS code
• Make sure RoomHistoryManager will work removing the .rc-scrollbars-view class
• Make sure useLegacyThreadMessageListScrolling will work properly when replacing the ScrollValues type
• Run some brute force tests in all places that uses CustomScrollbars

Before

After

It also fixes such small annoying visual issues:
