[Build] Add FIPS docker image for GovCloud (#117152)

- Adds docker image based on chainguard base fips image
- x86 only for now as the base image is x86 only
- the image does not provide any elasticsearch.yml configuration. for testing purposes you can follow the elasticsearch fips guide available at https://github.com/elastic/FIPSGuide/tree/main/elasticsearch

The image is shipped with:
- org.bouncycastle:bc-fips:1.0.2.5 and org.bouncycastle:bctls-fips:1.0.19 in Elasticsearch libs folder
- config/jvm.options.d/fips.options for fips specific JVM options
- fips_java.security file
- fips_java.policy

Out of scope:
- Add packaging test coverage (part of later PR as we want to provide that image for testing early and packaging tests require more general restructuring for support fips scenarios)
