internal/buildcfg: enable DWARF version 5 by default

This patch enables the DWARF version 5 experiment by default for most
platforms that support DWARF. Note that MacOS is kept at version 4,
due to problems with CGO builds; the "dsymutil" tool from older
versions of Xcode (prior to V16) can't handle DWARF5. Similar we keep
DWARF 4 for GOOS=aix, where XCOFF doesn't appear to support the new
section subtypes in DWARF 5.

Updates #26379.
