Rollup merge of #40870 - alexcrichton:stabilize-windows-subsystem, r=aturon

rustc: Stabilize the `#![windows_subsystem]` attribute

This commit stabilizes the `#![windows_subsystem]` attribute which is a
conservative exposure of the `/SUBSYSTEM` linker flag on Widnows platforms. This
is useful for creating applications as well as console programs.

Closes #37499
