RFR: 8259679: GitHub actions should use MSVC 14.28

[Aleksey Shipilev]

Current Windows GH Actions fails with:

configure: using /cygdrive/c/progra~2/micros~1/2019/Enterprise/vc/auxiliary/build/vcvarsx86_amd64.bat
configure: Setting extracted environment variables for x86_64
checking that Visual Studio variables have been correctly extracted... ok
checking for cl... [not found]
configure: error: Could not find a C compiler.
configure exiting with result code 1

I managed to figure out that MSVC build 14.27 is not really available. 14.28 is available instead. Note that Windows AArch64 build block already uses 14.28 in the same manner, so this change not only fixes the GH actions, it also keeps both blocks consistent.
