http-push: avoid new compile error

With the recent update in Git for Windows/ARM64 as of
https://github.com/git-for-windows/git-sdk-arm64/commit/21b288e16358
cURL was updated from v8.15.0 to v8.16.0, and the LLVM-based builds (but
strangely not the GCC-based builds) continuously greet me thusly:

  http-push.c:211:2: error: call to '_curl_easy_setopt_err_long' declared
  with 'warning' attribute: curl_easy_setopt expects a long argument
  [-Werror,-Wattribute-warning]
      CC builtin/apply.o
    211 |         curl_easy_setopt(curl, CURLOPT_INFILESIZE, buffer->buf.len);
        |         ^

     50 |               _curl_easy_setopt_err_long();                             \
        |               ^
  1 error generated.
  make: *** [Makefile:2877: http-push.o] Error 1

The easiest way to shut up that compile error (which is legitimate,
seeing as the `CURLOPT_INFILESIZE` options expects a `long` parameter,
but `buffer->buf.len` refers to the `size_t` attribute of a `strbuf`)
would be to simply cast the parameter to a `long`.

However, there is a much better solution: To use the
`CURLOPT_INFILESIZE_LARGE` option instead, which was added in cURL
v7.11.0 (see https://curl.se/ch/7.11.0.html) and which Git _already_
uses in `curl_append_msgs_to_imap()`.

This fix was the motivation for renaming `xcurl_off_t()` to
`cast_size_t_to_curl_off_t()` and making it available more broadly,
which is the reason why it is used here, too.
