This reverts commit 18c94fa. (#4065)

The use of lsp--point-to-position is not correct since there appears to be a lot of unfinished work regarding the use of the Position structure. currently this function always returns a plist and a lot of other code depends on this fact:

• lsp-mode/lsp-mode.el

  Line 6208 in 9ee4a2b

  (let ((cur-position (lsp-make-position :line (plist-get (lsp--cur-position) :line)

• lsp-mode/clients/lsp-csharp.el

  Line 195 in 9ee4a2b

  (let ((pos-line (plist-get (lsp--cur-position) :line))

in order to write lsp-lens--window-range like this, further refactoring work needs to be finished
