feat(perl-lsp): add stub perl_stdlib_data.c

- Define cbm_perl_stdlib_register with a REG_BUILTIN macro (php_stdlib shape)
- Register placeholder builtins (print, bless, ref) so the symbol links
- TODO(plan 22-02): full perlfunc + CPAN seed

+ * perl_stdlib_data.c — Perl stdlib + CPAN type data (stub).
+ *
+ * Strategy mirrors php_stdlib_data.c:
+ *   1. perlfunc builtins (print, bless, ref, ...) as global functions.
+ *   2. Curated, corpus-driven CPAN types (Moose, Moo, DBI, ...).
+ *
+ * This file is a placeholder: it registers just a couple of builtins so the
+ * cbm_perl_stdlib_register symbol exists and links through the lsp_all.c
+ * unity build. The full perlfunc + CPAN seed lands in a later plan.

+ * TODO(plan 22-02): full perlfunc + CPAN seed
