Sync package version of double-conversion between bazel and cmake (#20017)

* Sync package version of double-conversion between bazel and cmake

This fix tries to sync package version of double-conversion between
bazel and cmake.

The double-conversion package was added in 12102 and was reverted
in PR 15133. At that time the package version was 5664746 for both
bazel and cmake.

Later on, the double-conversion was re-introduced in PR 18746. The
package version of double-conversion in bazel has been advanced
to 3992066a95b823efc8ccc1baf82a1cfc73f6e9b8 but the version in cmake
remains the old 5664746.

This fix updates the double-conversion version in cmake so that
it is synced with the version (3992066a95b823efc8ccc1baf82a1cfc73f6e9b8) used in bazel.
