feat(payment.method): Add payment.mehot according to SAT
There was a module named l10n_mx_payment_method which adds this information, but we new changes in CFDI 3.3 it is not make sense to maitain a module to upload this information, besides all new SAT catalogos were loaded from this module. Then to keep order it was took the desicion of deleting l10n_mx_payment_method and merge its informaton here
merge l10n_mx_payment_method to l10n_mx
