Now it would list details of all KMS instances with additional
attributes `endpoint` and `version`. In the case of k8s-based
deployment the list would consist of a single entry.

This commit adds a `context.Context` to the
the KMS `{Stat, CreateKey, GenerateKey}` API
calls.
The context will be used to terminate external calls
as soon as the client requests gets canceled.
A follow-up PR will add a `context.Context` to
the remaining `DecryptKey` API call.

This commit adds a minimal set of KMS-related metrics:
```
# HELP minio_cluster_kms_online Reports whether the KMS is online (1) or offline (0)
# TYPE minio_cluster_kms_online gauge
minio_cluster_kms_online{server="127.0.0.1:9000"} 1
# HELP minio_cluster_kms_request_error Number of KMS requests that failed with a well-defined error
# TYPE minio_cluster_kms_request_error counter
minio_cluster_kms_request_error{server="127.0.0.1:9000"} 16790
# HELP minio_cluster_kms_request_success Number of KMS requests that succeeded
# TYPE minio_cluster_kms_request_success counter
minio_cluster_kms_request_success{server="127.0.0.1:9000"} 348031
```
Currently, we report whether the KMS is available and how many requests
succeeded/failed. However, KES exposes much more metrics that can be
exposed if necessary. See: https://pkg.go.dev/github.com/minio/kes#Metric

It would seem like the PR #11623 had chewed more
than it wanted to, non-fips build shouldn't really
be forced to use slower crypto/sha256 even for
presumed "non-performance" codepaths. In MinIO
there are really no "non-performance" codepaths.
This assumption seems to have had an adverse
effect in certain areas of CPU usage.
This PR ensures that we stick to sha256-simd
on all non-FIPS builds, our most common build
to ensure we get the best out of the CPU at
any given point in time.
This commit improves the listing of encrypted objects:
- Use `etag.Format` and `etag.Decrypt`
- Detect SSE-S3 single-part objects in a single iteration
- Fix batch size to `250`
- Pass request context to `DecryptAll` to not waste resources
when a client cancels the operation.

This commit adds support for bulk ETag
decryption for SSE-S3 encrypted objects.
If KES supports a bulk decryption API, then
MinIO will check whether its policy grants
access to this API. If so, MinIO will use
a bulk API call instead of sending encrypted
ETags serially to KES.
Note that MinIO will not use the KES bulk API
if its client certificate is an admin identity.
MinIO will process object listings in batches.
A batch has a configurable size that can be set
via `MINIO_KMS_KES_BULK_API_BATCH_SIZE=N`.
It defaults to `500`.
This env. variable is experimental and may be
renamed / removed in the future.

- remove some duplicated code
- reported a bug, separately fixed in #13664
- using strings.ReplaceAll() when needed
- using filepath.ToSlash() use when needed
- remove all non-Go style comments from the codebase

This is to ensure that there are no projects
that try to import `minio/minio/pkg` into
their own repo. Any such common packages should
go to `https://github.com/minio/pkg`
