Precompiles description

[jhelison]

Is your feature request related to a problem? Please describe.
Currently, on the docs, we don't explain all the different pre-compiles that exists on Kiichain

Describe the solution you'd like
Create pages for:

• IBC
• oracle
• wasmd

Pages describing the pre-compile:

• General description and objectives
• Function calls
• Queries

Describe alternatives you've considered
Kiichain source code is the only documentation currently

Additional context
More information can be found on Kiichain:

Hi @jhelison!

Would you assign this issue to me?

I have reviewed the precompiles in the repository and created documentation pages for each of the main precompiles (IBC, Oracle, Wasmd) as requested.

Each page includes:

• A general description and objectives of the precompile
• Supported function calls (with parameters and purpose)
• Supported queries (with example usage)

Let me know if you’d like any additional details or examples for a specific precompile!
