Fix out-of-bounds read on trailing backslash in wxRegEx::Replace()
wxRegExImpl::Replace() scans replacement.c_str() and does *++p after a
backslash. When the replacement ends in a lone backslash, that reads the
terminating NUL, the else branch appends it, and the loop's p++ then
steps one byte past the NUL so the *p condition reads out of bounds.

Keep a trailing backslash verbatim and stop before the increment.

Add a test checking that this doesn't result in ASAN errors any more.

Closes #26541.
