Extend the `gen_smb1_mapping` script to support generating sorted POSIX
error mapping tables for both ERRDOS and ERRSRV classes at compile time.
The script parses annotations from smberr.h to generate smb1_err_dos_map.c
and smb1_err_srv_map.c, which are included as the contents of the arrays
mapping_table_ERRDOS[] and mapping_table_ERRSRV[], respectively.
This ensures that the mapping logic remains synchronized with the source
headers and prepares for faster error lookups using binary search in the
future.

Check whether all elements can be correctly found in the array.
Introduce CONFIG_SMB1_KUNIT_TESTS for smb1maperror_test.ko since
smb1maperror.o is only built when CONFIG_CIFS_ALLOW_INSECURE_LEGACY
is enabled.
We are going to define 3 functions to check the search results, introduce
the macro DEFINE_CHECK_SEARCH_FUNC() to reduce duplicate code.

The ntstatus_to_dos_map[] array now contains the NT error strings,
making the nt_errs[] array redundant.
Introduce `struct ntstatus_to_dos_err` instead of an anonymous struct.
This allows cifs_print_status() to look up error strings directly
from a single table.
Remove nterr.c, as nt_errs[] was its only functional content.

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.

The current rule for smb2_mapping_table.c uses `$(call cmd,...)`, which
fails to track command line modifications in the Makefile (e.g., modifying
the command to `perl -d` or `perl -w` for debug will not trigger a rebuild)
and does not generate the required .cmd file for Kbuild.
Fix this by transitioning to the standard `$(call if_changed,...)` macro.
This includes adding the `FORCE` prerequisite and appending the output
file to the `targets` variable so Kbuild can track it properly.
As a result, Kbuild now automatically handles the cleaning of the
generated file, allowing us to safely drop the redundant `clean-files`
assignment.
