VersionSpec is the version specification for v2.

Changes from v1:

Adds a new FIELD_SAME_DEFAULT check, which requires that the new schema not change default values for fields. (Defaults values are a feature of proto2 and editions, but not in proto3 syntax.)

Adds new EXTENSION_NO_DELETE and PACKAGE_EXTENSION_NO_DELETE checks, to make sure that extensions are not deleted from a file or package, respectively. (In previous versions, an extension being deleted was simply undetected.)

Removes the following deprecated checks (but retains their replacements):

• FIELD_SAME_CTYPE
• FIELD_SAME_LABEL
• FILE_SAME_JAVA_STRING_CHECK_UTF8
• FILE_SAME_PHP_GENERIC_SERVICES
