functionapp: az cli disables build on deploy for windows function apps

Describe the bug https://github.com/Azure/azure-cli/pull/10706 effective disables remote builds for windows consumption plan function apps.

Changelog does not mention that new flag is for linux function apps only:

Added --build-remote flag for az functionapp deployment source config-zip to support remote build action during function app deployment.

Also no deprecation warning for have been given for windows consumption plan with SCM_DO_BUILD_DURING_DEPLOYMENT=true

Documentation[1] does not specify any ways to trigger npm install.

To Reproduce Running az functionapp deployment source config-zip --build-remote ... fails with Remote build is only available on Linux function apps

Alternative running az functionapp deployment source config-zip without --build-remote flag changes function app settings and does not trigger npm install:

Setting ENABLE_ORYX_BUILD to false
Setting SCM_DO_BUILD_DURING_DEPLOYMENT to false

Expected behavior After zip deployment function host should trigger npm install(or other installation method) like az cli did before the pull request.

Alternative fix: another way to trigger npm install after deployment with az cli should be documented.

Workrounds

• Trigger npm install manually in kudu console
• fetch publishing profile with az cli and trigger npm install through kudu REST API

@StrawnSC can you investigate - AFAIK no changes were to function app deployment that should regress this.
