This allows us to use `uv` for: 1. Installing a pinned Python version 2. Installing the dependency packages using `uv`'s pip compatible interface. 4. Bootstrapping `mach` without a Python installion on the host, using `uv run` This change also introduces a new 'composite' GitHub action to setup python in the different CI workflows. There is no support for externally managed python installations and virtual environments. These could be added in the future. Fixes servo#34095, servo#34547 Signed-off-by: Mukilan Thiyagarajan <[email protected]>

`mach` now [depends on `uv`][1] being already installed on the host to bootstrap the Python environment. This change updates the `Setting up your environment` to include the steps for installing `uv` on the host system. [1]: servo/servo#34632 Signed-off-by: Mukilan Thiyagarajan <[email protected]>
