Refactor utility functions related to pointers

[shuheiktgw]

What does this PR do?

Most of the pointer-related utility functions have been deprecated due to the introduction of generics. In this PR, I've refactored the code and removed most of them.

Motivation

Cleaning up the codebase.

🔵 Code Quality Violation

Condition could be directly returned (...read more)

In Go, it is considered unnecessary and less readable to write a conditional statement that returns true or false explicitly based on a condition. Instead, it is recommended to directly return the condition itself. Here's why:

1. Code simplicity and readability: Writing return condition directly conveys the intent of the code more clearly and reduces unnecessary verbosity. It is easier for other developers to understand your code at a glance without having to analyze additional conditional statements.
2. Avoidance of redundancy: Explicitly returning true or false based on a condition introduces redundancy in the code. Since the condition itself already evaluates to a boolean value (true or false), there is no need to include additional return true or return false statements.
3. Maintainability and refactoring: The direct return condition approach is more maintainable and flexible for future code changes. If the condition or the desired return value changes, it is easier to modify a single line rather than multiple lines of code. This minimizes the chances of introducing errors or inconsistencies during refactoring.

Therefore, it is recommended to simply use return condition instead of if condition { return true } return false. By doing so, you improve code readability, reduce redundancy, and ensure better maintainability of your Go code.
