fix(@angular-devkit/build-angular): resolve absolute output-path when using esbuild based builders

Prior to this change using an absolute path as a `output-path` resulted in the path to be combined with the workspace root instead of resolved which caused the output to be emitted in the incorrect directory or error in Windows.

Closes #26935
