The copy of props feels wrong, but could not get it working otherwise
with the box and borrow things 😅
Also I found that TSImportType was missing some entries for visitors and
codegen.
In the case of codegen I'm not really understand the need as all the
types seems to be dismissed?
Fix source mapping of Window-style line breaks in presence of Unicode chars.
`content.chars().nth(i + 1)` gets the `i + 1`th *char*, but `i` is a byte offset not a char offset.
The replacement `content.as_bytes().get(i + 1)` gets the `i + 1`th *byte*, and should also be faster as doesn't require iterating through `chars` again.
#2565 added source map support in codegen. But there was a bug in creating the line offset tables for Unicode. This PR fixes that.
This function could probably be made more efficient, but I think this at least makes it correct.
This gets all the new TS types working to the same level TS output was
before and fixes a bunch of other codegen

> A Use Strict Directive may not contain an EscapeSequence or
LineContinuation.
It is `Use Strict Directive` spec, but the `expression` of `Directive`
isn't original string value, it has error if using it to codegen, so
here using `directive` of `Directive` to codegen and not to escape it.
Here is crashed test cases.
``` js
'use str\
ict';
```
The babel will print the original string, I follow it and avoid using
`print_str` because it will escape string.
I also changed some code using the `expression` of `Directive` to check
`Use Strict Directive` .
This was incorrectly using raw for dynamically generated numbers like in
the minifier (
6e0bd52af1/crates/oxc_minifier/src/compressor/fold.rs (L280)
).
This ensures they are dynamically generated during codegen.
This does not investigate why `just example minifier` does not take the
`if MINIFY` branch.
