feat(p/json): JSON path support

[notJoon]

Description

Implemented a feature that parses JSONPath expression using a state machine and extracts data matching the specified path from the input JSON data.

JSONPath is an expression used to select and filter specific data within a JSON data. This implementation supports the basic functionalities of JSONPath.

Here's a table summarizing the supported JSONPath features now:

Symbol	Description	Example
Root Object($)	Represents the root object of the JSON. All paths start with this symbol	$.store.book[0].title
Wildcard(*)	Selects all elements of any object or array.	$.store.*
Subscript Operator([])	Selects a specific element of an array or object using an index or a key.	$.store.book[0]
Deep Scan(..)	Selects the specified property regardless of the depth in the JSON.	$..price
Slice Operator(:)	Selects elements within a range in an array.	$.store.book[0:2]

Currently, This implementation focuses on the basic functionality of JSON path expressions to prevent the size of PR is bigger. So, the filter expressions(?(@)) are not implemented yet. but this feature will be added with complex filtering and built-in functions.

I expect, with this JSONPath parser, users can easily extract and utilize desired information from within JSON data.

Hello @notJoon . Some CI tests from Sept. 3 failed. Maybe merge master again to see if they pass?

It causes an unknown panic, so I'll leave it in draft until I resolve it.

Only 3 failed tests this time :-) .

I think the "examples/fmt" failure is easy to fix. "Some gno files are not formatted, please run 'make fmt'."

Removed the review/triage-pending label because the author converted this PR to Draft status. When Draft status is removed, we will add the label again.
