Add stream-style logging macros

[dentiny]

Problem statement:

• Existing logging and assertion is kind of awkward, for example, it doesn't accept stream-style operation, meanwhile it uses string as the macro parameter, which means we have to concatenate the message beforehand.
  • (minor) It might hurts performance, I see a lot of the message construction is made by operator+, which could create temporary strings
  • (major) it reduces logging util usability

In this PR, I propose to add a new macro, which combines both assertion and logging with stream style operation.

@dentiny Thanks for sending this. We will take a look at it. It might make more sense to use a third-party header-only logger.

Thanks @apavlo for taking a look! It would be nice to support CHECK_EQ-like syntax, which

• Allows comparison logic
• Prints out value for lhs and rhs if comparison logic fails
• Code location (i.e. filename and line number) is included in the error message

For this PR, I mostly target at code simplicity w/o extra deps :)

Curious if there're any updates on this PR? :eyes:

@dentiny End of semester crunch. We will look at this soon.

If you can fix the CI then I think this is fine to merge!

Thank you @connortsui20 for the review! I think the code is benign so I simply suppress the linter warnings.
