[protobuf] protobuf v3.12.0

[jozefizso]

Update protobuf package to release v3.12.0

[LilyWangL]

@jozefizso Thanks for your PR. Now ignition-msgs5 build failed with the following error, it build depends on protobuf.
buildtrees\ignition-msgs5\src\sgs5_5.1.0-e593042925\src\Utility.cc : fatal error C1128: number of sections exceeded object file format limit: compile with /bigobj

[jozefizso]

The /bigobj switch is set in CMakeLists.txt already.

  # Allow big object
  add_definitions(/bigobj)

[jozefizso]

I added patch for ignition-msg5 to use /bigobj switch. This should make it compatible with protobuf 3.12.

Cool, thanks @jozefizso :)

Looks like this might have caused regressions when merged with other changes: https://dev.azure.com/vcpkg/public/_build/results?buildId=37252&view=artifacts&type=publishedArtifacts

Due to the following code, protobuf arm64-windows arm-uwp x64-uwp build failed on CI pipelines.

if(CMAKE_HOST_WIN32 AND NOT VCPKG_TARGET_ARCHITECTURE MATCHES "x64" AND NOT VCPKG_TARGET_ARCHITECTURE MATCHES "x86")
    set(protobuf_BUILD_PROTOC_BINARIES OFF)
elseif(CMAKE_HOST_WIN32 AND VCPKG_CMAKE_SYSTEM_NAME)
    set(protobuf_BUILD_PROTOC_BINARIES OFF)
else()
    set(protobuf_BUILD_PROTOC_BINARIES ON)
endif()

if(NOT protobuf_BUILD_PROTOC_BINARIES AND NOT EXISTS ${CURRENT_INSTALLED_DIR}/../x86-windows/tools/protobuf)
    message(FATAL_ERROR "Cross-targetting protobuf requires the x86-windows protoc to be available. Please install protobuf:x86-windows first.")
endif()

This error was not detected due to the cache on the CI, I will modify the ci.baseline.txt to fix this issue.
