unicode-bidi: plaintext never worked properly when there is a line wrapping in a 
span with unicode-bidi: plaintext.
The problem happens because constructBidiRunsForSegment does not have
 enough logic to understand the difference between line wrapping vs line
 breaking, the current patch just adds the necessary logic(e.g when a text has a
 line wrapping it needs to determine the directionality of the paragraph from the beginning of the isolatedInline)

Move SharedBuffer into blink_platform.dll

This CL moves SharedBuffer and its dependencies into platform.dll. This CL is
interesting because it's the first time that blink_platform.dll will depend on
the Platform API and the first time that it will export symbols as part of the
API.
