build: cherry-picks from main for dependencies and Windows build

Update to using build.ps1 on release/5.10 as well to get the complete
toolchain build on Windows. Switch to using update-checkout for checking
out the following dependencies:
- CURL
- ICU
- libxml2
- zlib

Update the CURL dependency to 8.4.0 to match 5.9.1.
