[clang] [Clang] Drop Shell Requirements (PR #165149)

[Aiden Grossman via cfe-commits]

https://github.com/boomanaiden154 created https://github.com/llvm/llvm-project/pull/165149

These are basically synonymous with marking windows as an unsupported platform at this point and should be removed in favor of such annotations. Removing the remianing annotations which should further unblock removing the feature altogether now that everything minus compiler-rt is using the internal shell by default. These were missed when making the tests compatible with the internal shell.

These are basically synonymous with marking windows as an unsupported
platform at this point and should be removed in favor of such
annotations. Removing the remianing annotations which should further
