* [vcpkg docs] Change how documenting port functions works
Instead of using `##`, use comment blocks for documentation.
Also, add some minor docs and change RST -> MD
so we actually get docs generated.
* add CI stuff
* regenerate docs
* fix vcpkg_find_acquire_program to not use _execute_process
* Update meson to a recent commit to fix a bug with 0.56
* rename static libraries built by meson by default on windows
* apply cmake variables detection to meson.
use native/cross files
make arm builds work.
* update munit
* fix fribidi
* fix _FLAGS variables
* set env SDKROOT and MACOSX_DEPLOYMENT_TARGET in configure_meson
* need osx env while building and configuring
* - remove unused env backup functions
- rename internal functions to be prefixed with _vcpkg_
- fix VCPKG_CHAINLOAD_TOOLCHAIN_FILE for ios/freebsd
* replace _vcpkg with vcpkg since _ has special meaning in functions
* rename functions to vcpkg_internal_meson_generate
* update control tool-meson
