Inlining string constant into f-string should be smarter

[lieryan]

Describe the bug

Inlining expression containing string constant into f-string should take into consideration the surrounding f-string's quote.

To Reproduce Steps to reproduce the behavior:

1. Code before refactoring:

msg = "hello"
s = f"foo: {msg}"

2. Inline "msg"

3. Expected code after refactoring, should be either:

s = f"foo: {'hello'}"

or maybe even special case the situation where

s = f"foo: hello"

4. Describe the error or unexpected result that you are getting

s = f"foo: {"hello"}"

which is not a valid code because the double quotes cannot be parsed properly by Python:

SyntaxError: f-string: expecting '}'
