Support bicep multi-line function calls

[jmservera]

Describe the feature

Bicep functions, like guid(), throw a parse error when split in multiple lines. Single line works well, but splitting the parameters in multiple lines improves readability.

Examples

This fails:

resource cognitiveServicesOpenAIUserForUser 'Microsoft.Authorization/roleAssignments@2020-04-01-preview' = {
  scope: azureOpenAI
  name: guid(
    azureOpenAI.id,
    principalId,
    resourceId('Microsoft.Authorization/roleDefinitions', '5e0bd9bd-7b93-4f28-af87-19fc36ad61bd')
  )
  properties: {
    roleDefinitionId: resourceId('Microsoft.Authorization/roleDefinitions', '5e0bd9bd-7b93-4f28-af87-19fc36ad61bd')
    principalId: principalId
    principalType: principalType
  }
}

While this works correctly:

resource cognitiveServicesOpenAIUserForUser 'Microsoft.Authorization/roleAssignments@2020-04-01-preview' = {
  scope: azureOpenAI
  name: guid(azureOpenAI.id, principalId,resourceId('Microsoft.Authorization/roleDefinitions', '5e0bd9bd-7b93-4f28-af87-19fc36ad61bd'))
  properties: {
    roleDefinitionId: resourceId('Microsoft.Authorization/roleDefinitions', '5e0bd9bd-7b93-4f28-af87-19fc36ad61bd')
    principalId: principalId
    principalType: principalType
  }
}

I'd like to see this as well. Happens a lot when doing some formatting with brackets ()[]. If I remember correctly it's also causing parsing error when a resource/module loop is ending with ] in a single line instead of }]
