Fix boards-manager install issues on Linux and Windows (#5898)

* Fix packaged python paths for Windows

Fixes #5881

The path to python.exe on Windows needs to change depending on whether
it is installed via the boards manager or GIT (similar to the compiler
paths).  Adjust accordingly.

* Add python-placeholder to make boardsmanager happy

An empty "python" directory will be created by the boards-manager
installer.  Required because all archs need all tools defined.

* Make the placeholder include a symlink for "python"

* Fix esptool windows python path

Fixes a typo in the python path for Windows for upload.

* Fix esptool windows python path

Fixes a typo in the python path for Windows for upload.

* Fix tools path when in GIT mode for upload
