[PATCH v2 02/12] smb/client: autogenerate SMB1 NT status to DOS error mapping

[huiwen.he@linux.dev]

From: Huiwen He <hehuiwen@kylinos.cn>

Introduce `gen_smb1_mapping` script to autogenerate the NT status to
DOS error mapping table for SMB1. This script parses nterr.h to
generate smb1_mapping_table.c, which is then directly included as
the content of the ntstatus_to_dos_map[] array at compile time.

The generated array is numerically sorted during the build process to
ensure a consistent structure, providing the necessary groundwork for
future introduction of binary search lookups.
