app/vlinsert: follow-up for 37ed1842ab
- Properly decode protobuf-encoded Loki request if it has no Content-Encoding header.
  Protobuf Loki message is snappy-encoded by default, so snappy decoding must be used
  when Content-Encoding header is missing.

- Return back the previous signatures of parseJSONRequest and parseProtobufRequest functions.
  This eliminates the churn in tests for these functions. This also fixes broken
  benchmarks BenchmarkParseJSONRequest and BenchmarkParseProtobufRequest, which consume
  the whole request body on the first iteration and do nothing on subsequent iterations.

- Put the CHANGELOG entries into correct places, since they were incorrectly put into already released
  versions of VictoriaMetrics and VictoriaLogs.

- Add support for reading zstd-compressed data ingestion requests into the remaining protocols
  at VictoriaLogs and VictoriaMetrics.

- Remove the `encoding` arg from PutUncompressedReader() - it has enough information about
  the passed reader arg in order to properly deal with it.

- Add ReadUncompressedData to lib/protoparser/common for reading uncompressed data from the reader until EOF.
  This allows removing repeated code across request-based protocol parsers without streaming mode.

- Consistently limit data ingestion request sizes, which can be read by ReadUncompressedData function.
  Previously this wasn't the case for all the supported protocols.

lib/protoparser: support zstd in all logs http ingestion, datadog and otel metrics protocols ()
This commit introduces common readers for multiple compression encoding algorithms. 

Currently, supported encodings are:
* zstd
* gzip
* deflat
* snappy

 It adds new common reader to the all VictoriaLogs ingestion protocols.
And updates opentelemetry metrics parsing for VictoriaMetrics components.

Also, it ports zstd stream parses from cluster branch.

lib/encoding/zstd: reduce the number of cached zstd.Encoder instances
Use the real compression level supported by github.com/klauspost/compress/zstd as a cache map key.
The number of real compression levels is smaller than the number of zstd compression levels.
This should reduce the number of cached zstd.Encoder instances.

lib/encoding/zstd: switch back from atomic.Pointer to atomic.Value for map[...]...
The map[...]... is already a pointer type, so atomic.Pointer[map[...]...] results in double pointer.

This is a follow-up for 140e7b6b74

all: replace atomic.Value with atomic.Pointer[T]
This eliminates the need in .(*T) casting for results obtained from Load()

Leave atomic.Value for map, since atomic.Pointer[map[...]...] makes double pointer to map,
because map is already a pointer type.

6c4ca89d75 lib/encoding/zstd: disable CRC checks in pure Go build
This should give slightly better compression and decompressions performance.
Additionally this shaves off 4 bytes per each compressed block.
