Add constants for each possible Kind value (KindNull, KindTrue, etc.).
Leave the values unchanged ('n', 't', etc.).
Update documentation to reference the symbols.

The fully streaming UnmarshalJSONFrom method and UnmarshalFromFunc
introduce an edge case where they can encounter EOF in the stream,
where it should be reported upstream as EOF rather than
ErrUnexpectedEOF or be wrapped within a SemanticError.
This is not possible with other unmarshal methods since the
"json" package would read the appropriate JSON value
before calling the custom method or function.
To avoid custom unmarshal methods from encountering EOF,
check whether the stream is already at EOF for top-level values
before calling the custom method.
Also, when wrapping EOF within a SemanticError, convert it
to ErrUnexpectedEOF to better indicate that this is unexpected.
Fixes #75802

This does the equivalent of CL 681177 for the Encoder.
It preserves the internal buffer between resets.

When operating under v1 semantics in the v2 implementation,
a extra data error should take precedence over any semantic error
that could theoretically occur within the value itself.
This change only affects code compiled under goexperiment.jsonv2.

The Decoder.Reset method is not preserving the internal buffer between
resets, causing buffer capacity to be lost and resulting in unnecessary
allocations when reusing decoders. This is particularly problematic when
decoding many small messages.
This commit fixes the Reset method to preserve the internal buffer. It
makes sure aliasing is removed if the buffer currently points to an
internal byte slice of a bytes.Buffer. It adds a TestDecoderReset test
structured into subtests to better validate the different scenarios.

This imports the proposed new v2 JSON API implemented in
github.com/go-json-experiment/json as of commit
d3c622f1b874954c355e60c8e6b6baa5f60d2fed.
When GOEXPERIMENT=jsonv2 is set, the encoding/json/v2 and
encoding/jsontext packages are visible, the encoding/json
package is implemented in terms of encoding/json/v2, and
the encoding/json package include various additional APIs.
(See #71497 for details.)
When GOEXPERIMENT=jsonv2 is not set, the new API is not
present and the encoding/json package is unchanged.
The experimental API is not bound by the Go compatibility
promise and is expected to evolve as updates are made to
the json/v2 proposal.
The contents of encoding/json/internal/jsontest/testdata
are compressed with zstd v1.5.7 with the -19 option.
Fixes #71845
For #71497
