SQLite3::Database#execute_batch fails with non-ASCII characters

[Math2]

Before v2.0.0, the following used to work:

require 'sqlite3'

db = SQLite3::Database.new ':memory:'

db.execute_batch %{
  CREATE TABLE test(t TEXT);
  INSERT INTO test VALUES ('héhé');
}

But now fails with:

/usr/home/mathieu/.gem/ruby/3.2/gems/sqlite3-2.0.0/lib/sqlite3/statement.rb:31:in `encode': "\xC3" from ASCII-8BIT to UTF-8 (Encoding::UndefinedConversionError)
        from /usr/home/mathieu/.gem/ruby/3.2/gems/sqlite3-2.0.0/lib/sqlite3/statement.rb:31:in `initialize'
        from /usr/home/mathieu/.gem/ruby/3.2/gems/sqlite3-2.0.0/lib/sqlite3/database.rb:166:in `new'
        from /usr/home/mathieu/.gem/ruby/3.2/gems/sqlite3-2.0.0/lib/sqlite3/database.rb:166:in `prepare'
        from /usr/home/mathieu/.gem/ruby/3.2/gems/sqlite3-2.0.0/lib/sqlite3/database.rb:250:in `execute_batch'
        from ./test.rb:5:in `<main>'

@Math2 Thanks for reporting this. I'll take a look!

Bisecting indicates a9a89f8 is the commit that introduced this behavior. It looks like the "tail" string comes back from #prepare as ASCII-8BIT because we're doing the encoding slightly differently.

I've got a fix, just writing up some tests and I'll create the PR shortly.

See #526 for the proposed fix.
