GH-37328: [Python] Add a function to download and extract timezone database on Windows (#38179)

### Rationale for this change

There is a section in the [Arrow C++ documentation with the instructions](https://arrow.apache.org/docs/dev/cpp/build_system.html#runtime-dependencies) on how to download and extract text version of the IANA timezone database and on Windows. We should provide a function in PyArrow that a user would call to download and extract the timezone database from Python.

### What changes are included in this PR?

Function `download_tzdata_on_windows()` added to python/pyarrow/util.py that downloads and extracts timezone database to a standard location in `%USERPROFILE%\Downloads\tzdata` on Widnows.

### Are these changes tested?
Yes.

### Are there any user-facing changes?
No.
* Closes: #37328
