fix multiple use of name param in sqlite

[doron050]

This pull request refactors the TransformQueryText method in SqliteDriver.cs. The method is responsible for converting sqlc's parameter syntax (? or ?1, ?2, etc.) to the named parameter format (@paramName) used by Microsoft.Data.Sqlite.

Key Changes:

The core of this change is an optimization of how both numbered and positional parameters are handled:

1. Numbered Parameter Handling (?1, ?2):

   • Before: The method would loop through each parameter, creating a new Regex object on each iteration to replace all instances of a specific numbered placeholder (e.g., ?1). This was inefficient due to repeated regex compilation inside a loop.
   • After: The new implementation is much more performant. It now builds a dictionary mapping parameter numbers to their names and then uses a single Regex.Replace call with a MatchEvaluator. This allows for all numbered placeholders to be replaced in a single pass over the query string.

2. Positional Parameter Handling (?):

   • Before: The logic for positional parameters also used Regex.Replace inside a loop, replacing one placeholder at a time.
   • After: This has been refactored to use a MatchEvaluator with a parameter enumerator, providing a cleaner and more efficient way to handle sequential replacements.

Looks good:) Had one comment, but no critical. Can take in a differnt PR

you can extract the regex to a partial static class, like in one of the other drivers. See here for example. We can fix in another PR though
