This turns the constexpr constructors into templates to silence errors when constexpr isn't valid. We are also switching to 12.2 for GCC/cmake tests to prevent regressions (9.5 and 13.1 are already tested by GCC/bazel tests).
Fixes#12807

Formerly, they had their own fast path. Now they share the chunked processing of all fields. This makes chunked processing more effective as an optimization and also eliminates replicated code for repeated fields.

This PR replaces the descriptor name validation regex with a validation method. This change allows the `System.Text.RegularExpressions` engine to be trimmed away in published apps that do standard protobuf serialization.
There are some other usages of `Regex` in Google.Protobuf, but they in `JsonParser`. They are only included in a published app if `JsonParser` is used.
Another benefit is a slightly faster app startup time. The removed regex was compiled, which has a high-ish fixed cost.

When we are running the destructor, we do not have an Arena. Since the Arena
is a runtime property, the compiler may not be able to optimize it out.

This implements some cross-linking for traversing back up the tree, and some uniformity to aid templatized descriptor helpers. Later changes will make the previously public fields private

In both cases a `size_t` was being converted to a `uint32_t`. These headers are used from application code, or at least from generated code, and the application may be compiling with more warnings enabled than normal.
Closes#12762

This parser reduces binary code size between 1% and 20%, particularly of debug and sanitized builds, while improving aggregate performance.
Micro benchmarks may regress, but large system performance improves.

DLLs get in the way of making these tables constexpr in the general case because cross-DLL references are not constant.
However, we need descriptor.proto tables to be constexpr so we keep constexpr there were we know it works. They do not reference other DLLs.
