Adapt Hibernate native support for HHH-17643
Browse files Browse the repository at this point in the history
This commit adapts Hibernate native support to handle
the changes performed as part of HHH-17643 which impacts
Hibernate versions 6.4.3+ and 6.2.21+.

It ignores the BytecodeProvider services loaded by the
service loader feature in order to default to the
"no-op" provider with native, and makes the substitutions
more lenient when a substituted field or method does not
exist.

gh-32314 is expected to remove the need for such
substitutions which are not great for maintainability
by design.

Closes gh-32311
