BUG: byteorder option in to_stata is not honoured when writing strL data

[cmjcharlton]

• closes BUG: Invalid Stata file is generated if byteorder='big' is specified and strings are saved as strL type #58969 (Replace xxxx with the GitHub issue number)
• Tests added and passed if fixing a bug or adding a new feature
• All code checks passed.
• Added type annotations to new arguments/methods/functions.
• Added an entry in the latest doc/source/whatsnew/vX.X.X.rst file if fixing a bug or adding a new feature.

I have created a local variable to indicate whether the file is being saved to the native byteorder in two places, but am happy to calculate this once in __init__ and store in self for later access if you prefer.

I think this would be preferable. Over time we've wanted to avoid mutating state variables in methods if possible

Thanks, that's useful to know. I have now changed this.
