Add support for azure devops resources (project/repo/build)

Issues:
Im working on automating creation of CI/CD environments in AzureDevops and looking at using Terraform's [azuredevops](https://registry.terraform.io/providers/microsoft/azuredevops/latest/docs) provider. This is a great solution but has limitation; For example there isn't support to create pipelines. Bicep supports azure devops pipelines, but nothing else (as far as I can tell). To accomplish what I want I'll have to use a mix of tools (Terraform/Bicep/REST API) and it will be complicated.

Proposed Solution:
Add arm template and bicep support to cover AzureDevops resource creation (Projects, Git Repo, Build, Pipelines). This will simplify similar solutions by consolidating work into one tool (bicep).

------====Example config====--------
```bicep
resource my_project 'Microsoft.DevOps/project' {
name: 'My Awesome Project'
description: 'All of my awesomee things'
}

resource my_git_repo 'Microsoft.DevOps/repository' {
project_id: my_project.id
name: 'My Awesome Repo'
initialization: {
init_type: 'Clean'
}
}

resource my_build_def 'Microsoft.DevOps/build_definition' {
project_id: my_project.id
name: 'My Awesome Build Pipeline'
path: '\\'

repository: {
repo_type: 'TfsGit'
repo_id: my_git_repo.id
branch_name: my_git_repo.default_branch
yml_path: 'azure-pipelines.yml'
}
}
```

No files, tests, or entry points are named in the issue. Start by surveying how Bicep models existing Azure resources and reviewing the Azure DevOps resources proposed here; done means support for creating projects, Git repositories, build definitions, and pipelines through ARM/Bicep.
