Fix T78259: Proportional editing does not work in particle editing

This is a long-standing bug, possibly proportional editing never worked
in particle mode.

Some parameter definitions in the transform code are scattered and
sometimes duplicated.

Proportional editing is a parameter that depends only on the Convert
type and not `spacetype`, `CTX_` or `obedit_type`.
