TODO : Deprecate paste crate usage in error.rs

[coderfender]

@martin-g , ready for your review

[coderfender]

@comphead , I took the more laborious approach to remove paste crate and replace the macro defs with elaborated arguments than trying to find a new crate. Almost all other past crate usage is in tests / non critical path of code with one major usage in UDWF and Error macros

[coderfender]

Fixed a typo simple_udfw instead of simple_udwf

[coderfender]

Thank you for the review @martin-g . Fixed the typo with udfw in the docs aignature and fixed macro signature docs per review comments. Take a look whenever you get a chance . Thank you

[comphead]

we would also need to rollback #20850

[coderfender]

@comphead , thank you for the review. I was wondering if we could do it in a different PR but I believe we can do it in the current PR too. I just pushed a commit to unignore the rust warning in git wf. Please take a look whenever you get a chance
