tools: make mkssldef ignore DEPRECATEDIN

[refack]

Make mkssldef ignore deprecation. e.g. TLSv1_2_* that were deprecated in openSSL_1_1:

node/deps/openssl/openssl/util/libssl.num

Line 157 in 49b0f7f

TLSv1_server_method 158 1_1_0 EXIST::FUNCTION:DEPRECATEDIN_1_1_0,TLS1_METHOD

Fixes: #20369

Checklist

• make -j4 test (UNIX), or vcbuild test (Windows) passes

LGTM with a comment.

Can you check that the zeroth field is what you expect it to be?

if ',' in meta[3]:
  fst, meta[3] = meta[3].split(',')
  assert fst.startswith('DEPRECATEDIN')

The above assumes at most two fields. You could also filter out all deprecation tags:

words = meta[3].split(',')
words = [word for word in words if not word.startswith('DEPRECATEDIN')]
assert len(words) == 1
meta[3] = words.pop()

Maybe add the testcase from #20369?

Since this didn't land, I've opened an alternative PR which adds the deprecated categories to the list of categories to export (rather than trying to ignore them): #25991.
