Optimizer details does not allow inliner flag

[dileepfrog]

Description

The JSON input documentation shows a boolean flag inliner under settings.optimizer.details. However setting this flag causes the error CompileError: Unknown key "inliner". A cursory glance at the code shows that it is indeed not included in the keys here though it does get parsed here.

Potentially related to #10354 (stripping coverage instrumentation)
