script: Add line number argument to module script compilation functions (#39544)

Browse source 
Script: added ```line_no``` as argument to both
```fetch_inline_module_script()``` & ```compile_module_script()``` to
fix the inline script reporting wrong line issue
([#39415](https://github.com/servo/servo/issues/39415)).

Originally, the function ```compile_module_script()``` hardwires the
value 1 when invoking ```CompileOptionsWrapper::new()```. This is fine
if the script is written in separate JS file, but for inline scripts, it
will cause confusion if the ```<script>``` tag doesn't start from line
#1.

```line_no``` is obtained from ```line_number```, a member variable from ```HTMLScriptElement```. 

Credits to @jdm for actually pointing out which functions to fix.

Testing: Created a WPT test for this change, specifically: ```tests/wpt/tests/html/semantics/scripting-1/the-script-element/module/evaluation-error-5.html```.

Fixes: issue [#39415](https://github.com/servo/servo/issues/39415)
