Remove build isolation in wheel builds

[jameslamb]

Description

Currently, RAPIDS projects build wheels with build isolation, like pip wheel ..

With build isolation, the build tool (in our case, pip wheel), creates a virtual environment and installs of the package's build-time dependencies into it. That virtual environment is created at a random location on each build, which means source files included from other wheels (like the rmm headers from the librmm wheel) are found at a different path on each build in CI.

Path changes lead to cache misses with sccache, and therefore longer-running and more memory-intensive builds.

As more of RAPIDS build-time dependencies are provided wheels (e.g. #33), this problem is going to get worse (see #33 (comment)).

This issue tracks the work of removing build isolation in RAPIDS wheel-building CI jobs.

Benefits of this work

Better sccache hit rate = faster, cheaper CI (contributes to #95).

Stronger guarantees that packages built in CI are actually installed at test time (i.e. would close #79).

Acceptance Criteria

• all RAPIDS wheels builds in CI build with --no-build-isolation

Approach

Follow the approach from rapidsai/cuspatial#1473.

Notes

These can be done in any order.
