Document also that PyUnicode_READ_CHAR() supports reading the trailing null byte.

Add tests on PyUnicode_READ_CHAR().

gh-156939: Document that PyUnicodeObject ends with null character (GH-157708)

Document also that PyUnicode_READ() and PyUnicode_READ_CHAR()
accept reading the trailing null character, and that PyUnicode_GetLength()
doesn't count the trailing null character.
(cherry picked from commit 4d3b405)
