This reverts commit ac8fe0e9.

Reason for revert: crbug.com/986879

Original change's description:
> android: Reintroduce and rework ModernLinker.
> 
> This is partially a revert of two commits:
> - 53a10113: "Delete unused file:
>    base/android/linker/android_dlext.h"
> - fdb31883: "Use the LegacyLinker instead of the
>    ModernLinker"
> 
> ModernLinker has been reworked, especially the native side. Notable changes:
> - The library is only loaded once, not twice in the browser process
> - Relocations are always shared between the browser process and the other ones.
> 
> This is enabled only on N+ for Chrome.apk, neither for Monochrome nor for TriChrome.
> 
>              on Q, further commit will trim it as well.
> 
> Binary-Size: Increase due to bringing back ModernLinker. Required to save memory
> Bug: 979638
