Updates #3644.

BREAKING CHANGE: SCIMService.ProvisionAndInviteSCIMUser now takes a new ProvisionAndInviteSCIMUserRequest by value instead of *SCIMUserAttributes.

ProvisionAndInviteSCIMUser (POST /scim/v2/organizations/{org}/Users) used the response type SCIMUserAttributes as its request body. That type has response-only fields (ID, Meta) and Roles, none of which are in the request schema. This PR adds a request type with exactly the properties of the request schema, the same way as the existing UpdateProvisionedOrgMembershipRequest for PUT /scim/v2/organizations/{org}/Users/{scim_user_id}.

Two commits:

1. feat - Add the properties of the scim-user response schema that SCIMUserAttributes was missing: organization_id (OrganizationID), profileUrl (ProfileURL), and operations (Operations, which reuses UpdateAttributeForSCIMUserOperations because the item schema is the same op/path/value). The GetSCIMProvisioningInfoForUser test now decodes them.
2. refactor! - Add ProvisionAndInviteSCIMUserRequest and pass it by value. userName, name, and emails are required in the schema, so they are not pointers and have no omit option. The optional slices Schemas and Groups use omitzero. SCIMUserAttributes is removed from body-allowed-pointer-types, and the test checks the request body with testJSONBody.

The method name already matches the GitHub docs operation name ("Provision and invite a SCIM user"), so it is not renamed.

Verified locally: go build ./..., go vet -tags integration ./test/integration/, example module build, go test ./github/, generated files idempotent, custom-gcl 0 issues, and script/check-schema-fields.sh reports nothing for the SCIM types. (It reports 4 new warnings for EnterpriseUpdateBudget, but master reports the same 4 since the openapi_commit update in #4693, so they are not from this PR.)
