Extend the spp_custom_filter to support the SPMIS, Farmer Registry, and demo modules

[gonzalesedwin1123]

The spp_custom_filter module provides a way for certain fields set with the "allow_filter" attribute from appearing in domain filters. Currently, only a minimal list of fields of the res.partner model are defined with this attribute in the spp_customer_filter_ui module.

This needs to be extended to the spp_base (SPMIS), spp_farmer_registry, and the demo data generator modules. Set the fields for the res.partner model defined in these modules with the "allow_filter" attribute set to "True". Refer to the list of fields below:

1. spp_base (SPMIS):

• tags_ids

2. spp_farmer_registry:

• farmer_national_id
• farmer_postal_address
• marital_status
• highest_education_level

3. spp_mis_demo:

• z_ind_grp_is_single_head_hh
• z_ind_grp_is_hh_with_medical_condition
• z_ind_grp_is_hh_with_children
• z_cst_indv_medical_condition

4. spp_farmer_registry_demo:

• marital_status
• highest_education_level
• household_size
