Missing file during initialization of module_wind_mav does not raise error

[sgremmo]

Bug description During the initialization of the new Ma&Archer wind farm parametrization, even if the layout file of the wind turbines (windturbines-ll_txt) is missing, the simulation starts and executes. However, the simulation runs without including the wind turbines. No warning or errors are raised.

To Reproduce Steps to reproduce the behavior:

1. WRF version: 4.6.1 (commit d66e442fccc04111067e29274c9f9eaccc3cef28)
2. Use compiler and version: gfortran 11.4.0
3. Use namelist options windfarm_opt = 0 , 0 , 2 , windfarm_ij = 2,

Expected behavior An error should be raised if windturbines-ll.txt is missing

Proposed solution: Include a check in initialization function of module_wind_mav to check if the file windturbine-ll.txt can be opened. Stops otherwise.
