[double-conversion] Upgrade CMake 3.5

[WangWeiLin-MV]

Fix #43973

Failed due to https://cmake.org/cmake/help/latest/release/4.0.html#deprecated-and-removed-features

Compatibility with versions of CMake older than 3.5 has been removed.

Backport google/double-conversion@101e1ba, upgrading min version to 3.5.

Checklist

• Changes comply with the maintainer guide.
• SHA512s are updated for each updated download.
• The "supports" clause reflects platforms that may be fixed by this new version.
• Any fixed CI baseline entries are removed from that file.
• Any patches that are no longer applied are deleted from the port's directory.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is added to each modified port's versions file.

Test

The port installation tests pass with the following triplets:

• x64-linux (CMake 4.0.0-rc2)

Isn't it easier to just pass -DCMAKE_POLICY_VERSION_MINIMUM=3.5 instead of adding a patch?

Thanks for the reminder, it works.

 vcpkg_cmake_configure(
     SOURCE_PATH "${SOURCE_PATH}"
+    OPTIONS
+        -DCMAKE_POLICY_VERSION_MINIMUM=3.5
+    MAYBE_UNUSED_VARIABLES
+        CMAKE_POLICY_VERSION_MINIMUM
 )

Given the patch provided on upstream, I prefer download patch.

The method that passing option can be applied to other ports.

The CMake 4.0 aspect came up also in #44086.
I came to the conclusion that patching might be preferred, #44086 (comment).
