Handle clang AST loc nodes with elided 'line' in introspect codegen.
Apple's math.h (included directly by mujoco.h) contains an anonymous union
whose clang-JSON 'loc' lacks the 'line' key (clang elides it when unchanged
from the previous node), crashing AstProcessor._make_anonymous_key with a
KeyError during bindings regeneration on macOS. glibc's math.h has no such
union, so this never bites on Linux.
Fall back to an offset-based key for line-less nodes; these system-header
structs are never referenced by MuJoCo types, so the key only needs to be
unique.
