TypeScript does not allow type parameters on constructors:
```ts
class A {
constructor<T>(t: T) {} // <- should be an error

```
Here's a comparison snippet on:
1. [TypeScript

(syntax error).
2. [SWC

This PR makes OXC behave exactly like `tsc`, with a little test case.

perf(sourcemap): improve perf of search_original_line_and_column ( #7926 )
...
this seems to show a decent speed up on perf.
the thinking behind this change is:
1. subsequent calls to `search_original_line_and_column` will **never**
look at back at lines it has already searched
2. binary search is faster in this case as typically `idx` is only
increased by a small amount
Given this, we can skip checking a bunch of lines (that will never
return true) improving performance.
This is a very hot path.
```

fix(transformer/class-properties): run other transforms on static properties, static blocks, and computed keys ( #7982 )
...
Large re-architecting of class properties transform. Split transform into 3 phases:
1. Transform instance properties when entering class.
2. Transform private fields during traversal of class body.
3. Transform static properties and static blocks when exiting class.
This ensures that code which has to be moved outside of the class (static property initializers, static blocks, computed keys) can get transformed by other transforms before they're moved out.
Also fixes a problem where we previously registered private properties too early - on entering the class, rather than the class *body*, so private fields in `extends` clause of a nested class were misinterpretted.
