docs: Fixing bad unicode sequence in Javadocs.

The source file /external/icu/icu4j/main/classes/…/
has a comment with the character sequence '\u0000', which is being
output verbatim to a Javadoc comment the generated file
java/android/icu/text/ . (See bug b/32309442)

That character sequence is being output as a null byte in the
generated HTML file:,%20java.lang.String)

Besides generating bad documentation (the sequence shows up as "\u"
instead of "\u0000"), this also means we won't be able to check the
generated docs in to Piper as text files.

Per instructions from JS, I've modified the external file, run the
script to generate the java/android/icu file from it, and included
both files in this CL. I've also generated the Javadoc from the
modified file and staged it to:


NOTE: Currently, a double-backslash sequence is incorrectly output to
the Javadoc as a double-backslash instead of being treated as an
escape character. I filed a separate bug about that, b/32335850
