Fix issue 7828: enabling the binary logger adds console output

[fanhaipeng]

Fixes #7828

Context

Binary logger option overrides verbosity by diagnostic and prints a line even verbosity is set to quiet.

Changes Made

The fix introduces a variable to store the original verbosity, if the "original verbosity" is quiet, it suppresses the console output when binary logger is requested.

Hi @Forgind / @rainersigwald, the failed test case is from MultiplePlugins, should not be related to my change, what next step do you recommend? Thanks

Microsoft.Build.Engine.UnitTests.ProjectCache.ProjectCacheTests.MultiplePlugins System.IndexOutOfRangeException : Index was outside the bounds of the array.

@fanhaipeng, I reran it, and it passed.

/cc: @dfederm for awareness on the flaky test.
