Fix password encoding when generating PDFs.

Per https://crbug.com/pdfium/1194, PDFium accepts passwords in either
Latin1 or UTF8 encoding, and will re-encode, if necessary, to correctly
decrypt PDFs. When the encrypted PDFs are copied and saved, the copy
needs to be encrypted with the password with the proper encoding.

Do so by remembering the re-encode status in CPDF_SecurityHandler. Then
use that knowledge in GetEncodedPassword() to encode passwords properly.
Re-enable CPDFSecurityHandlerEmbedderTest code that was disabled due to
this issue, and add new TODOs for test cases that still do not work due
to other issues.
