fix build.ps1 script execution error on cmd due to whitespace

[himanshu8088]

build.cmd unable to execute on command prompt due to white space issue in the file path.

Powershell doesn’t natively support a parameter for a script to run. The default command-line argument is “-command,” which defines the command as though you had typed it at the prompt.
Now although, "%~dp0eng\build.ps1"is quoted in a double quote but it is treated as a string and will not be executed. I found a bug with the code in a file due to the mentioned issue.

The call operator (&) allows you to execute a command, script, or function, I made PR for the bug fix.

Fix #35458

@jkoritzinsky can you please review the PR and make sure this doesn't break your multi-arch/configurations work that you were doing?

[jkoritzinsky]

Validated that this works with the multi-arch/multi-config build feature.

Issue is #13610 (remote executor timing out)
