Add MSYS2 (UCRT64) support and drop Bam support on Windows

[Bamcane]

This PR changes a lot, in order to support MSYS2.
I wanted to use MSYS2 (mingw-w64) at first, but then I found it didn't support the feature we used in the code:

	// normal with positional arguments
	str_format(aBuf, sizeof(aBuf), "%1$s %2$s", "first", "second");
	EXPECT_STREQ(aBuf, "first second");

	// reverse
	str_format(aBuf, sizeof(aBuf), "%2$s %1$s", "first", "second");
	EXPECT_STREQ(aBuf, "second first");

	// duplicate
	str_format(aBuf, sizeof(aBuf), "%1$s %1$s %2$d %1$s %2$d", "str", 1);
	EXPECT_STREQ(aBuf, "str str 1 str 1");

so I changed to apply ucrt64 instead.
Windows bam support was removed as bam hasn't support MSYS2 yet.
Also it's difficult to support it as it hasn't any docs to read.
Though my name is Bamcane, I still have to remove it.
But I would add it back as it supports MSYS2. :3

This PR changes how the package is built:
it now uses CPack exclusively to package the binaries.
The dynamic libraries for SDL2, FreeType, OpenGL, and OpenSSL are now included in the package.
The workflows now also build on Windows Server 2022 (the windows-latest is Windows Server 2025)
