Adds a flag to run_binary_size_analysis.py to disable format checks

This change is needed for compatibility with the Flutter Engine's
use of a new Android NDK. The new Android NDK includes a new clang
toolchain which does a better job of classifying various
contributors to a binary's size, but which fails the compatibility
checks in the script. The intention of the compatibility checks is
to exclude versions of tooling that are too old not versions that
are too new. The compatibility check is also redundant with
failure modes later in the script. To avoid breaking any usage
of this script in the Dart tree, however, the check is retained
by this change, and instead a flag is added that skips it. This
is preferable to expanding on the questionable use of regular
expressions that implement the check to capture the strings
emitted by a continually updating toolchain.
