Investigate Log Task Inputs performance https://github.com/microsoft/msbuild/issues/2200

Need to be able to control LogTaskInputs independently of Verbosity or /bl https://github.com/microsoft/msbuild/issues/5233

Binary logger should respect verbosity https://github.com/microsoft/msbuild/issues/4543

Very high memory consumption during build (4GB) with binary log enabled https://github.com/microsoft/msbuild/issues/2168

Binlog causes detailed summary messages output to console https://github.com/microsoft/msbuild/issues/4409

Text log format doesn't distinguish between item metadata and new items https://github.com/microsoft/msbuild/issues/3966

Set MSBUILDTRUNCATETASKINPUTS environment variable to 1 to truncate task inputs: https://github.com/microsoft/msbuild/pull/5210/files#diff-5f4088c7b8512fa52f7faf88f89661f3R122
