cli and bootstrap improvements.

[mshima]

Overview of the feature request

There is a series of cleanups and improvements to cli and bootstrap.

• improve generation speed ng(x)-default takes 4m30s to generate at v7. Due to Major regression on ng-default sample generation. #20782, it was possible to reduce to 1m20s optimizing mem-fs-editor usage.
• drop fork usage and convert to await/async Rework cli support #21048
• replace yeoman-generator's in constructor option definition with a custom made definition and parsing More cli rework #21077
• apply new option definition at main generators
• optimize transforms (requires mem-fs, yeoman-environment and yeoman-generator) improvements.
• modularize @GeneratedByJHipster transform.
• check the possibility of converting frontend translations transforms
• convert jdl command into a generator. simplified implementation and adds blueprint support.
• integrate import-jdl into jdl command.
• don’t look for jhipster at local dir and require the standard npx jhipster to run the locally installed jhipster.
• move options load from the constructor to the initializing priority at main generators
