lib/fs: remove unused IsEmptyDir()
This function became unused after the commit 43b24164ef

all: consistently use %w instead of %s in when error is passed to fmt.Errorf()
This allows consistently using errors.Is() for verifying whether the given error wraps some other known error.

lib/fs: do not panic at windows at dir deletion (#4132)
Windows doesn't allow to remove dir with opened files. Usually it's a case for snapshots, hard cannot be removed if file is openned.
With this change, dir will be renamed and properly deleted at the next process start.
It's recommended to restart vmstorage/vmsingle for snapshots deletion completion periodically.

lib/fs: add MustReadDir() function
Use fs.MustReadDir() instead of os.ReadDir() across the code in order to reduce the code verbosity.
The fs.MustReadDir() logs the error with the directory name and the call stack on error
before exit. This information should be enough for debugging the cause of the error.

lib/fs: convert CreateFlockFile to MustCreateFlockFile
Callers of CreateFlockFile log the returned err and exit.
It is better to log the error inside the MustCreateFlockFile together with the path
to the specified directory and the call stack. This simplifies
the code at the callers' side while leaving the debuggability at the same level.

lib/fs: substitute ReadFullData with MustReadData
Callers of ReadFullData() log the error and then exit.
So let's log the error with the path to the filename and the call stack
inside MustReadData(). This simplifies the code at callers' side,
while leaving the debuggability at the same level.

lib/fs: rename WriteFileAtomically to MustWriteAtomic
Callers of this function log the returned error and exit.
So let's just log the error with the given filepath and the call stack
inside the function itself and then exit. This simplifies the code
at callers' place while leaves the same level of debuggability in case of errors.

lib/fs: replace MkdirAllIfNotExist->MustMkdirIfNotExist and MkdirAllFailIfExist->MustMkdirFailIfExist
Callers of these functions log the returned error and then exit. The returned error already contains the path
to directory, which was failed to be created. So let's just log the error together with the call stack
inside these functions. This leaves the debuggability of the returned error at the same level
while allows simplifying the code at callers' side.

While at it, properly use MustMkdirFailIfExist instead of MustMkdirIfNotExist inside inmemoryPart.MustStoreToDisk().
It is expected that the inmemoryPart.MustStoreToDick() must fail if there is already a directory under the given path.

lib/fs: replace WriteFileAndSync with MustWriteAndSync
When WriteFileAndSync fails, then the caller eventually logs the error message
and exits. The error message returned by WriteFileAndSync already contains the path
to the file, which couldn't be created. This information alongside the call stack
is enough for debugging the issue. So just use log.Panicf("FATAL: ...") inside MustWriteAndSync().
This simplifies error handling at caller side a bit.

lib/storage: skip blocks outside the configured retention during search
Blocks outside the configured retention are eventually deleted during background merge.
But such blocks may reside in the storage for long time until background merge.
Previously VictoriaMetrics could spend additional CPU time on processing such blocks
during search queries. Now these blocks are skipped.
