Subject: [PATCH 1/8] [lldb] colorize symbols in image lookup
This creates the method PutCStringColorHighlighted for Stream class,
which highlights searched symbols in red color for the image lookup command.
A new shell test was added to verify functionality. Relevant methods were
updated to accept the searched pattern/symbol as a parameter.
