Xcode: Restore suppression of header maps
In commit 8527f42b96 (Xcode: Explicitly disable deprecated user include
path feature, 2023-01-31, v3.26.0-rc1~7^2) we dropped the Xcode build
setting `USE_HEADERMAP = NO` because Xcode 14's "Build Documentation"
feature (`xcodebuild RUN_DOCUMENTATION_COMPILER=YES`) fails in some
cases without header maps. However, enabling header maps causes Xcode
to add `-iquote .../foo.hmap` and `-I .../bar.hmap` flags that can
change the intended header file search order based on the contents of
the header maps. This can break existing projects. Restore the
`USE_HEADERMAP = NO` setting to fix the header file search order.
Further investigation will be needed to resolve the problematic cases
with the Xcode 14 "Build Documentation" feature. Meanwhile projects
encountering such cases can set the `XCODE_ATTRIBUTE_USE_HEADERMAP`
target property to `YES` themselves.
Fixes: #24418
Issue: #24379
