feat: Add Terraform support for Chronicle Parser and ParserExtension

[govisingh-dotcom]

Description

This pull request introduces Terraform support for two new resources under the Chronicle ParserService API surface:

1. google_chronicle_parser: Manages Chronicle custom parsers (updatable, server-assigned IDs).
2. google_chronicle_parser_extension: Manages Chronicle parser extensions (immutable, server-assigned IDs).

These resources utilize the standard regionalized control plane endpoint https://{{location}}-chronicle.googleapis.com/v1beta/ to ensure correct GFE routing, and implement short-ID mapping using the id_from_name.tmpl custom flattener for their server-assigned UUID identifiers.

Key changes include:

• Resource definition in mmv1/products/chronicle/Parser.yaml.
• Resource definition in mmv1/products/chronicle/ParserExtension.yaml.
• HCL test configuration in mmv1/templates/terraform/examples/chronicle_parser_basic.tf.tmpl and chronicle_parser_full.tf.tmpl.
• HCL test configuration in mmv1/templates/terraform/examples/chronicle_parserextension_basic.tf.tmpl and chronicle_parserextension_full.tf.tmpl.
• Added official REST API reference and custom parser guides inside the references metadata section for both resources.
• Implemented ignore_read_extra for asynchronous validation properties (state, validation_report, validation_stage, state_last_changed_time, extension_validation_report) to prevent eventual-consistency timing flakiness during ImportStateVerify.

Tested

To address reviewer feedback and ensure robust validation of all optional, nested, and complex UDM blocks, we added four automated acceptance tests (two per resource).

Furthermore, to guarantee safe parallel execution in the GitHub CI presubmits and prevent Spanner locking collisions, each test has been mapped to a completely unique prebuilt log type:

• TestAccChronicleParser_chronicleParserBasicExample (WINDOWS_DHCP)
• TestAccChronicleParser_chronicleParserFullExample (LINUX_DHCP)
• TestAccChronicleParserExtension_chronicleParserextensionBasicExample (CISCO_DHCP)
• TestAccChronicleParserExtension_chronicleParserextensionFullExample (AKAMAI_DHCP)

All 4 tests successfully compiled and PASSED concurrently in parallel in the developer workstation sandbox:

=== RUN   TestAccChronicleParserExtension_chronicleParserextensionBasicExample
=== RUN   TestAccChronicleParserExtension_chronicleParserextensionFullExample

Multiple resources added

This PR adds multiple new resources: google_chronicle_parser, google_chronicle_parser_extension. This makes review significantly more difficult. Please split it into multiple PRs, one per resource.
An override-multiple-resources label can be added to allow merging.
