Prior to this patch '0' would be dropped as the config values default to 0. Some json values are hex and the string '0' wouldn't match '0x0' as zero. Add a more robust is_zero test to drop these event terms. When encoding numbers as hex, if the number is between 0 and 9 inclusive then don't add a 0x prefix. Update test expectations for these changes. On x86 this reduces the event/metric C string by 58,411 bytes.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
