Needs MarlinFirmware/TMCStepper#7

[dbuezas]

Forgot to mention: this PR switches to (my branch of the libs)

HAS_TRINAMIC_CONFIG                    = TMCStepper=https://github.com/dbuezas/TMCStepper/archive/refs/heads/dbuezas/tmc-2240-temperature-reading.zip

for testing.
As @thisiskeithb well mentions, it requires MarlinFirmware/TMCStepper#7 before merging (and obviously switching back to Marlin's branch of the driver)

@dbuezas @thisiskeithb — Indeed those things are true.
