[Improvement]: Improve the Handling record default values in compiler

[warunalakshitha]

Description

At the moment, we are creating a function, a function pointer, and a global variable for each record’s default value. This approach consumes considerable memory and processing time. We need to optimize it by invoking the function directly instead.

Initial changes have been pushed to https://github.com/warunalakshitha/ballerina-lang/tree/refactor_record_default_fps.

Since we are currently working on the native interpreter, these changes will be ported to the native implementation. Therefore, the Java implementation is kept on hold.

Closing this since we will not proceed with this task.
