Subject: [PATCH] [ci] Use pip to install cmake and ninja on Windows

Chocolatey's community feed is prone to rate-limiting, 503 Service
Unavailable, and gateway timeouts on CI runners. Installing cmake and
ninja wheels via `pip` is significantly faster and avoids dependency
on community.chocolatey.org.

See: #27511
