fix: upload with params

[OS-pedrogustavobilro]

Description

Fixes a bug where uploadFile with non-empty httpOptions.params would result in an error:

java.lang.IllegalStateException: Cannot set request property after connection is made

The cause being IONFLTRConnectionHelper#setupConnection was writing params to the connection's outputStream for PUT and POST requests (which are typically for upload), and later we tried to call connection.setRequestProperty, but the connection was already ongoing, causing the exception.

The fix involved changing how params are passed. For multipart/form-data, the params are written in the body in that Content-Type's format, as it was already happening with httpOptions.formData(which may not actually be used atm, but was left for backwards compatibility). For any other kind of request, since the body for upload file will contain binary data, we set the params in the url, like it already happens for download.
