John Guo db9f47d942 refract(gerror): add ITextArgs interface and its implements, mainly for i18n that needs text and args separately (#4597)
This pull request refactors the error handling code to improve support
for error text formatting with arguments, making it easier to retrieve
both the error message template and its arguments (useful for i18n and
structured error handling). It introduces the new `ITextArgs` interface,
updates error constructors to store format strings and arguments
separately, and adds methods to retrieve them. Several usages and tests
are updated to reflect these changes.

### Error formatting and argument support

* Introduced the `ITextArgs` interface to allow errors to expose their
text template and arguments separately, supporting advanced use cases
like internationalization (`errors/gerror/gerror.go`).
* Updated the `Error` struct to include an `args` field for error
arguments, and added methods `TextWithArgs()`, `Text()`, and `Args()` to
retrieve formatted error text, the template, and arguments respectively
(`errors/gerror/gerror_error.go`).

* Changed all error creation and wrapping functions (e.g., `Newf`,
`Wrapf`, `NewCodef`, etc.) to store the format string and arguments
separately, rather than pre-formatting the error text
(`errors/gerror/gerror_api.go`, `errors/gerror/gerror_api_code.go`).

* Updated the `Option` struct and related constructor to handle error
arguments (`errors/gerror/gerror_api_option.go`).

### Code and test improvements

* Updated formatting and equality checks to use the new methods for
retrieving formatted error text and arguments, ensuring consistent
behavior (`errors/gerror/gerror_error.go`,
`errors/gerror/gerror_error_format.go`).

* Improved unit tests to verify the new interface and argument handling,
including tests for the `ITextArgs` interface
(`errors/gerror/gerror_z_unit_test.go`).
* Minor code cleanup, such as removing unused imports and updating
comments for clarity (`errors/gerror/gerror_api.go`,
`errors/gerror/gerror_api_code.go`,
`errors/gerror/gerror_error_json.go`).

These changes make error handling more flexible and maintainable,
especially for scenarios where error messages need to be localized or
programmatically inspected.
