* Added getBacktraceInfo(), which returns the backtrace information
from the ANGLE code, including the addresses and the symbols if
possible
* Returns the data in an instance of the new class BacktraceInfo.
* In order to access this function, backtrace_utils.h has been
included in vk_utils.h
* New GN flag to make use of this feature:
* angle_enable_unwind_backtrace_support
* Current only available on Android (debug mode)
* If the flag is disabled, getBacktraceInfo() returns an empty
object.
* Added functions in util/ (per platform) to print the BacktraceInfo
data.
* Example of usage:
angle::printBacktraceInfo(angle::getBacktraceInfo());
* Minor edit: Moved cstdint from android_util.cpp to its header.
