Description

Lazy load cosmiconfig-typescript-loader

Motivation and Context

To avoid loading cosmiconfig-typescript-loader (and consequently ts-node/jiti) when not required (i.e. when the user has no typescript-based config file). Refer #3256 (comment). This unblocks the users facing #3256 and improves perf.

How Has This Been Tested?

Manually tested on my project with the patch. The CI already has tests for TS-based config.

Types of changes
