[vcpkg] Improve vcpkg::Files::Filesystem error handling (#6919)
* [vcpkg] Modify Filesystem::remove and Filesystem::rename to not throw.

* [.gitignore] Ignore new VS2019 CMake integration default location

* [.gitignore] Ignore CMakeSettings.json in toolsrc

* [vcpkg] Time external processes called with System::cmd_execute

* [vcpkg] Work around VS2019 CMake bug

* [vcpkg] Fix several unused variable warnings.

* [vcpkg] Improve error handling in vcpkg::Files::Filesystem

Always require either std::error_code or LineInfo to print better errors.

* [vcpkg] Fixup missing return value.

Drive by fix: silence warnings in tests.

* [vcpkg] Fix exiting in error_code overload

Drive by fixes for /analyze with VS2019
