chore: add a poc script for generating dtype combinations

[gunjjoshi]

Resolves None.

Description

What is the purpose of this pull request?

This pull request:

• adds a proof of concept to auto-generate valid dtype pairs.
• The valid combinations are then written in src/addon.c and lib/types.js.
• adds some meta-data in package.json of ceil, ceilf, cceil and cceilf. For now, I have only modified the relevant dtype fields in the meta-data of these 4 packages.

Please note that the meta-data in scalar math kernels of ceil are not completely correct. I have modified the input and output dtype fields only, which were required as of now.

We are skipping those dtypes which are currently not present here: https://github.com/stdlib-js/stdlib/tree/develop/lib/node_modules/%40stdlib/ndarray/base/unary#c-apis

This script generates the following matches table, which contains only the valid combinations:

I checked the generated functions here: https://github.com/stdlib-js/stdlib/tree/develop/lib/node_modules/%40stdlib/ndarray/base/unary#c-apis, and all of them do exist.
