Make upload.py compatible with existing FS upload (#6788)

Browse Source 
* Make upload.py compatible with existing FS upload

PR #6765 introduced an incompatibility with the existing Java uploaders
for SPIFFS and LittleFS,  breaking them because of the upload.py
parameter format change to support single stage erase/upload.

Add in patch to silently eat the single --end and to parse the write
address and filename properly as generated by calls from the plugins,
while retaining compatibility with the current IDE changes.

* Clean upload.py, make platform use write_flash

Make upload.py more concise and pythonic.

Use the "write_flash" argument in platform.txt for uploads instead of
assuming anything that is a file is the bin to upload.
