Well, there are a couple options, again using ":argdo" to iterate
over all the files. If you want to keep lines that contain
"backslash u hex-digit hex-digit hex-digit hex-digit", you can do

:set hidden
:argdo v/\\u\x\x\x\x/d

then review your changes and either save/abandon the changes.

Alternatively, if you have your original file and just want to keep
the "=" lines even if they don't have hex digits on them (might be
integers or something else?), you can preprocess with

:argdo v/=/d

to delete all the lines that don't contain an "=". You can then run
the previously-provided command to change the "=" to ",".

If you just want to delete those lines starting with a hash, you can use

:argdo g/^\s*#/d

to delete them.
