This pull request introduces significant improvements to the DM database
driver, especially around insert operations, and refines documentation
and tests to reflect these changes. The main focus is enabling support
for "replace" and "insert ignore" operations using DM's `MERGE`
statement, improving type reporting for table fields, and updating
documentation for clarity and accuracy.
### DM Driver Insert Operations
* Added support for `Replace` and `InsertIgnore` operations in the DM
driver by internally mapping them to DM's `MERGE` statement. This
enables upsert and insert-ignore behavior for DM databases, improving
compatibility with other drivers.
* Implemented helper methods (`doMergeInsert`, `doInsertIgnore`, and
`getPrimaryKeys`) to generate correct `MERGE` SQL statements and
automatically detect primary keys when needed.

* Updated the logic for building update values and SQL generation to
ensure correct behavior for both upsert and insert-ignore cases.

### Table Field Type Reporting
* Improved the DM driver's `TableFields` method to report column types
with length/precision (e.g., `VARCHAR(128)` instead of just `VARCHAR`),
aligning with expectations and other drivers.

* Updated related unit tests to expect the new type format for DM table
fields.
### Documentation Updates
* Removed outdated or redundant documentation in both English and
Chinese driver README files, and clarified supported features and
limitations for DM and other drivers.

* Refactored and restored unit tests for DM driver insert operations,
including tests for `Save`, `Insert`, and the new `InsertIgnore`
functionality to ensure correct behavior and compatibility.

This pull request standardizes the use of the Go 1.18+ `any` type alias
instead of `interface{}` throughout the codebase. The change improves
code readability and aligns with modern Go best practices. The update
touches many files, including core data structures, code generation
templates, logging utilities, and test data, ensuring consistency across
all usages.
**Type alias migration to `any`:**
* Replaced all instances of `interface{}` with `any` in core data
structures such as `garray` and in generated model structs (e.g.,
`TableUser`, `User1`, `User2`) to modernize type usage.
