  Backtrace print methods should be able to change stack depth at runtime

Reviewed by Tim Horton.

Currently, developers can change the stack depth printed by the
WTFReportBacktrace family of functions statically, but this also causes
a lot of rebuilding, which can be time consuming.

Instead, this patch provides two variants to the backtrace reporter
methods that take the desired stack depth as an argument, allowing
developers to reflect these changes at runtime (and not take compile
time hits). Namely, these functions are WTFReportBacktraceWithStackDepth
and WTFReportBacktraceWithPrefixAndStackDepth.

This patch also takes the liberty to pull out the framesToShow and
framesToSkip variables into translation unit constants within
Assertions.cpp, promoting better variable hygiene.
