Add intl support for windows

[crazywhalecc]

What does this PR do?

ICU is built using vcpkg from static-php-cli-hosted. Since vcpkg integration has not yet been implemented, use solution 1 to temporarily support intl extension. The current implementation is very straightforward.

Closes #435

Sorry to bother you, but I don't have a working test case or existing project to test intl extensions on windows. I would be grateful if you could test it and provide feedback.
