Fix quoted identifiers in the generate_base_model macro for BigQuery

[dbeatty10]

resolves #205
resolves #193

Problem

There's some code that adds quoted identifiers for bigquery in a hard-coded fashion. It doesn't handle when a column name in BigQuery needs to be quoted such as a reserved keyword or a column that starts with a number.

Solution

Use adapter.quote to create a case-sensitive quoted identifier for column names since it is designed precisely for this type of use-case.

From CI for BigQuery:

23:43:04  3 of 23 START test test_generate_base_models_case_sensitive .................... [RUN]


with source as (

    select * from {{ source('codegen_integration_tests__data_source_schema', 'codegen_integration_tests__data_source_table_case_sensitive') }}

),

renamed as (

    select
        `My_Integer_Col`,
        `My_Bool_Col`

    from source

)

select * from renamed
