Revert "[stduuid] Adding new port stduuid (#16382)"

[BillyONeal]

This reverts commit e201002. As the port has been in the repo for less than 24 hours I'm trying to just revert it.

There are several problems with this port I missed on initial review that cause breakage:

• This port vendors a copy of MS-GSL which broke CI last night: https://dev.azure.com/vcpkg/public/_build/results?buildId=59537

The following files are already installed in D:/installed/x86-windows and are in conflict with stduuid:x86-windows

Installed by ms-gsl:x86-windows
include/gsl/gsl
include/gsl/gsl_algorithm
include/gsl/gsl_assert
include/gsl/gsl_byte
include/gsl/gsl_util
include/gsl/multi_span
include/gsl/pointers
include/gsl/span

• This port has features that control "alternatives", and doesn't imbue the alternative into the installed tree, violating https://github.com/microsoft/vcpkg/blob/master/docs/maintainers/maintainer-guide.md#do-not-use-features-to-implement-alternatives
