localedata: CLDRv29: update LC_ADDRESS.country_num values

This updates a few locales based on CLDR v29 data.

Add missing fields:
  as_IN: changing to 356
  dv_MV: changing to 462
  kk_KZ: changing to 398
  my_MM: changing to 104
  rw_RW: changing to 646
  tt_RU: changing to 643

Update ones that are wrong:
  dz_BT: changing BHU to 064
  en_PH: changing 360 to 608
  km_KH: changing 418 to 116
  ky_KG: changing 643 to 417
  tr_CY: changing 792 to 196
  wo_SN: changing 450 to 686

As a result of fixing these, I had to update country_ab[23]:
  dz_BT: changing BHU to BTN
  en_PH: changing ID/IDN to PH/PHL
  km_KH: changing LA/LAO to KH/KHM
  ky_KG: changing KY/KYR to KG/KGZ
  tr_CY: changing TR/TUR to CY/CYP
  wo_SN: changing MG/MDG to SN/SEN

Pad with leading zeros to match the standard and other locales:
  ber_DZ: changing 12 to 012
  ca_AD: changing 20 to 020
  en_AG: changing 28 to 028
  hy_AM: changing 51 to 051
  li_BE: changing 56 to 056
  wa_BE: changing 56 to 056

I hand checked the first two sets against ISO 3166-1 directly.
