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.

I've removed the previous implementation now, and have kept only the latest approach, as discussed, for the sqrt function. Now, along with the scripts, we have a few more files that would be helpful:

@stdlib/math/special/scripts/dtype_hierarchy.js : To find out which dtype to prefer, such as, preferring float64 over float32, in order to compute in higher precision.
@stdlib/math/special/scripts/function_database.json : Contains input & output dtypes, output policy and scalar kernels for each function.
@stdlib/ndarray/base/unary/data/funstion_list.json : To verify if the calculated ndarray kernel is actually available in ndarray/base/unary or not.

I tried running the same script for sin, and it gives the same dtype pairs as given for sqrt, as their input and output dtype policies are same. Here's the generated addon.c and types.js for sin.

@kgryte I've made the changes, as we discussed.

We now have math/special/scripts/generate_dtypes_database.js, which reads math/special/scripts/function_database.json and generates math/special/scripts/dtypes_database.json.
The config.js file that we had previously along with the scripts, is now within the math/special/scripts/function_database.json, so that the scripts are independent.

This file is now updated, based on the new script. We now have all the mostly-safe pairs, excluding the dtypes that we currently do not support (complex32, float16, uint8c).

While generating types.js and addon.c, I had disabled this check, as based on our discussion, we currently don't have all the ndarray kernels that we want to support.

In this PR, I have cleaned up the whole workflow for floor as of now, and if that is correct, I'll update it for sqrt and sin too.

Now, we are able to generate the following files:

src/addon.c
lib/types.js
lib/data.js
lib/meta.json
lib/types.json

I have included all the above generated files for floor, fibonacci, sin and sqrt in this PR now.
