Windows: Update icu-easyrpg to 67.1

[carstene1ns]

This is untested! Brings our custom icu on par with vcpkg upstream. (The easyrpg specific part - custom data file and static data packaging - is retained)

Fixes #94. The actual fix is updating to automake 1.16, if needed, we could apply this without updating the rest as a quick fix. See also: https://github.com/microsoft/vcpkg/pull/13980/files

Split out the automake update now, since it unbreaks the toolchain build. The actual update here can stay longer as it needs testing.

Sorry, forgot about this PR. I do now a test build and will report back if the Player works, thanks.

I'm currently unable to test it because CMake refuses now to find 32-bit fmt o_O. I try to find the problem.

There is another build failure: Could you also add the following lines to the build.cmd please? On the server I added a hack for this months ago because yasm was not found but looks like there is now an upstream fix for this:

CMake Error at installed/x64-windows-static/share/yasm-tool-helper/yasm-tool-helper.cmake:16 (message):

The fmt error was just me not reading. CMake requires now for Visual Studio solutions that the architecture is specified via "-A" argument.
