fix(typescript-angular): skip null and undefined fields in non-exploded object query params

Since #22459 non-exploded object query param goes through concatHttpParamsObject, and it calls toString() on every field
So {name: 'John', age: undefined} throws TypeError: Cannot read properties of undefined (reading 'toString') while request is built, same for null field or null item inside array field
explode: true and deepObject already skip such fields, and before #22459 they were skiped for every object param

Now null/undefined field is skipped together with its key, and null/undefined array items are dropped
Object where every field is undefined gives filter=, same as empty array gives ids= in existing spec

Added cases to api.query_param_form.spec.ts in typescript-angular-v20 sample, comma one fails on master with that TypeError
In regenerated samples only query.params.ts changes

Follow up to cubic note on #24964, I left it out of scope there

Fixes #22575

Summary by cubic

Fixes a TypeError in TypeScript Angular generated clients when non-exploded object query params contain null or undefined fields.

Bug Fixes

  • Null and undefined fields are skipped with their keys, null/undefined array items are dropped, and array fields with no remaining items are skipped entirely, matching explode: true and deepObject behavior.
  • Adds tests covering undefined fields, null array items, and empty arrays in exploded and non-exploded form query params.
