[pavelsavara]

This is version B)

• refactor new eng/native.props
• fix corehost/build.cmd
• use STATIC_LIB_DESTINATION and move all JS outputs there
• split System.Native.Browser-Rollup and System.Native.Browser-NpmInstall into it's own Common\JavaScript\CMakeLists.txt
• split browserhost into libBrowserHost.a, so that it could be linked later on customer machine
• removed native brotli from WASM build (for Mono too)
• install into sharedFramework
  • libcoreclr_static, libclrinterpreter, libgcinfo_unix_wasm, libcoreclrminipal, libnativeresourcestring, libcoreclrpal
  • libSystem.Native, libSystem.Native.TimeZoneData, libSystem.Native.TimeZoneData.Invariant,
  • libSystem.Globalization.Native, libicuuc, libicui18n, libicudata
  • libSystem.IO.Compression.Native, libz
  • libSystem.Native.Browser, libSystem.Runtime.InteropServices.JavaScript
  • libBrowserHost, dotnet.js, dotnet.runtime.js
  • minipal
• update eng/liveBuilds.targets to consume it from $(CoreCLRSharedFrameworkDir)

Fixes #120188
