Add support for writing ports of Ignition Robotics libraries and port…

…s for ignition-cmake0 and ignition-math4 (#7781)

* Add ignition-modularscript port

Modeled after the qt5-modularscript port, this port just contain
ignition_modular_library, an helper CMake function to simplify the
process of writing port of C++ libraries developed by the Ignition
Robotics project ( https://ignitionrobotics.org ).

* Add ignition-cmake0 port

* Add ignition-math4 port

+## # ignition_modular_library
+##
+## Download and build a library from the Ignition Robotics project ( https://ignitionrobotics.org/ ).
+##
+## ## Usage:
+## ```cmake
+## ignition_modular_library(NAME <name>
+## VERSION <version>
+## SHA512 <sha512>
+## [REF <ref>]
+## [HEAD_REF <head_ref>]
+## [PATCHES <patches>])
+## ```
+##
+## ## Parameters:
+## ### NAME
+## The name of the specific ignition library, i.e. `cmake` for `ignition-cmake0`, `math` for `ignition-math4`.
+##
+## ### VERSION
+## The complete version number.
+##
+## ### SHA512
+## The SHA512 hash that should match the downloaded archive. This is forwarded to the `vcpkg_from_bitbucket` command.
+##
+## ### REF
+## Reference to the tag of the desired release. This is forwarded to the `vcpkg_from_bitbucket` command.
+## If not specified, defaults to `ignition-${NAME}${MAJOR_VERSION}_${VERSION}`.
+##
+## ### HEAD_REF
+## Reference (tag) to the desired release. This is forwarded to the `vcpkg_from_bitbucket` command.
+## If not specified, defaults to `ign-${NAME}${MAJOR_VERSION}`.
+##
+## ### PATCHES
+## A list of patches to be applied to the extracted sources.
+## This is forwarded to the `vcpkg_from_bitbucket` command.
+##
+## ## Examples:
+##
+## * [ignition-cmake0](https://github.com/Microsoft/vcpkg/blob/master/ports/ignition-cmake0/portfile.cmake)
+## * [ignition-math4](https://github.com/Microsoft/vcpkg/blob/master/ports/ignition-math4/portfile.cmake)
