openexr 2.x: avoid conflict in PkgConfigDeps

[SpaceIm]

Summary

Changes to recipe: openexr/2.x

Motivation

Avoid conflict between files generated by PkgConfigDeps for openexr 2.x on case-insensitive file systems.

closes #24559

Details

PkgConfigDeps generate OpenEXR.pc file for openexr_ilmimf component , while an unwanted openexr.pc file is generated by default for the "global" component. To avoid conflict on case-insensitive file systems like Windows, we enforce an another custom pkg_config_name for this global component.
