feat: added static type casting

[morpheuschoo]

Added:

• Implemented support for C-style cast expressions (type) expression
• Support all numeric conversions between integral and floating-point types

To add:

• Validation for legal type conversions with appropriate warnings for potentially unsafe casts

Have you tested Support all numeric conversions between integral and floating-point types ? From what I can see this won't actually work. I just ran a simple test:

#include <source_stdlib>

int main() {
  float x = (int) 10.5;
  print_float(x);
}

what we print is 10.5, what it should be printing is 10 because of the conversion float -> int -> float.

Please ensure that your code does as it claims before putting it up for review, if not leave it in draft.

the originalDataType type here does not seem to be used anywhere. How does the type conversion (e.g. int-> float) actually work in that case?

These variables do not seem to be used anywhere. What is their purpose?
