sky130: updated variables in CSL config.tcl files

Update deprecated variables to conform to latest LibreLane:

* `PLACE_SITE_WIDTH` and `PLACE_SITE_HEIGHT` have been deprecated since OpenLane 2.0.0b16.
  Now automatically extracted from PLACE_SITE.
* `FP_WELLTAP_CELL` and `FP_ENDCAP_CELL` have been deprecated since OpenLane 2.0.0b17.
  The new variables have the `FP_` prefix removed.
* `SYNTH_DRIVING_CELL_PIN` has been deprecated,
  instead use `SYNTH_DRIVING_CELL` with format `{cell}/{port}`.
* added `SYNTH_CLK_DRIVING_CELL` variable set to `clkinv`.
* `SYNTH_MIN_BUF_PORT` was deprecated, instead use `SYNTH_BUFFER_CELL`
  with format `{cell}/{input_port}/{output_port}`.
* `SYNTH_TIEHI_PORT`/`SYNTH_TIELO_PORT` are deprecated,
  instead use `SYNTH_TIEHI_CELL`/`SYNTH_TIELO_CELL`
  with format `{cell}/{port}`.
* `CELL_CLK_PORT` has been deprecated since OpenLane 2.0.0a24,
  it is not used in the current version.
* `FILL_CELL` and `DECAP_CELL` were renamed to `FILL_CELLS` and `DECAP_CELLS` since LibreLane 3.0.0.
* `RE_BUFFER_CELL` is not used in LibreLane.
* Instead of `DIODE_CELL_PIN`, use `DIODE_CELL` with format `{cell}/{port}`.
* `FAKEDIODE_CELL` is not used by LibreLane.
* `ROOT_CLK_BUFFER` not used in LibreLane (probably supposed to do what `CTS_ROOT_BUFFER` does).
* `CTS_CLK_BUFFER_LIST` was deprecated, use `CTS_CLK_BUFFERS` instead.
* `FP_PDN_RAIL_WIDTH` was deprecated, use `PDN_RAIL_WIDTH` instead.
* `CTS_MAX_CAP` is unnecessary, LibreLane will extract it from `CTS_CLK_BUFFERS`.
* `CTS_CLK_BUFFER_LIST` was deprecated, instead use `CTS_CLK_BUFFERS`.
