Using centralized package management for vcxproj (#43920)

## Summary of the Pull Request
This pull request updates the build system for several native and
managed projects, modernizing NuGet package management and improving
code analysis configuration. The main changes involve switching from
legacy `packages.config` and manual `.props`/`.targets` imports to
PackageReference style for native projects, updating package versions,
and streamlining code analysis settings.

**Build system modernization and package management:**

* Migrated native projects (`PowerToys.MeasureToolCore.vcxproj`,
`FindMyMouse.vcxproj`) from legacy `packages.config` and manual
`.props`/`.targets` imports to NuGet PackageReference style, simplifying
dependency management and build configuration. This includes removing
the `packages.config` file and related import/error logic, and
introducing `PackageReference` items for required packages.

* Updated the centralized package versions in
`Directory.Packages.props`, adding new entries for `boost`,
`boost_regex-vc143`, `Microsoft.Windows.ImplementationLibrary`, and
`Microsoft.WindowsAppSDK.Foundation` to support the new build system and
dependencies.

**Code analysis improvements:**

* Added configuration to both native and managed projects
(`PowerToys.MeasureToolCore.vcxproj`, `MeasureToolUI.csproj`) to
suppress specific warnings (81010002) and exclude NuGet cache files from
code analysis, reducing noise and improving build performance.

**Project reference and output handling:**

* Updated the managed project (`MeasureToolUI.csproj`) to handle native
project outputs more robustly, ensuring the WinMD and DLL files are
available at runtime and configuring the project reference to avoid
assembly reference issues.

**Compiler configuration:**

* Enhanced C++ compiler settings in `Cpp.Build.props` to treat
angle-bracket includes as external, disable warnings and analysis for
external headers, and optimize build performance.
