Adopt special review process officially (#1347)

There are occassionally PRs that improve CDT in areas where there
is not enough current Eclipse CDT committer experience to provide
detailed reviews. Therefore the Eclipse CDT project adopted
(in [Oct 2023 call](https://hackmd.io/@jonahgraham/cdt-call-october-11-2023)
and reaffirmed in [Oct 2025 call](#1340))
that such if the code looks correct and it is sufficiently tested
it is ok to accept these changes.

Examples of previous times this policy has been adopted include
[PR #587](#587 (comment)),
[PR #581](#581 (review))
and others, particularly in the
[language support category](https://github.com/eclipse-cdt/cdt/pulls?q=is%3Apr+is%3Aclosed+label%3Alanguage+).

This policy can be referenced by a CDT committer/reviewer in the approval process.
