erofs: simplify compression configuration parser

Move erofs_load_compr_cfgs() into decompressor.c as well as introduce
a callback instead of a hard-coded switch for each algorithm for
simplicity.

Pull erofs updates from Gao Xiang:
"In this cycle, a xattr bloom filter feature is introduced to speed up
negative xattr lookups, which was originally suggested by Alexander
for Composefs use cases.

Additionally, the DEFLATE algorithm is now supported, which can be
used together with hardware accelerators for our cloud workloads. Each
supported compression algorithm can be selected on a per-file basis
for specific access patterns too.

There are also some random fixes and cleanups as usual:

- Support xattr bloom filter to optimize negative xattr lookups

- Support DEFLATE compression algorithm as an alternative

- Fix a regression that ztailpacking pclusters don't release properly

- Avoid warning dedupe and fragments features anymore

- Some folio conversions and cleanups"

erofs: DEFLATE compression support

Add DEFLATE compression as the 3rd supported algorithm.

DEFLATE is a popular generic-purpose compression algorithm for quite
long time (many advanced formats like gzip, zlib, zip, png are all
based on that) as Apple documentation written "If you require
interoperability with non-Apple devices, use COMPRESSION_ZLIB. [1]".

Due to its popularity, there are several hardware on-market DEFLATE
accelerators, such as (s390) DFLTCC, (Intel) IAA/QAT, (HiSilicon) ZIP
accelerator, etc. In addition, there are also several high-performence
IP cores and even open-source FPGA approches available for DEFLATE.
Therefore, it's useful to support DEFLATE compression in order to find
a way to utilize these accelerators for asynchronous I/Os and get
benefits from these later.

Besides, it's a good choice to trade off between compression ratios
and performance compared to LZ4 and LZMA. The DEFLATE core format is
simple as well as easy to understand, therefore the code size of its
decompressor is small even for the bootloader use cases. The runtime
memory consumption is quite limited too (e.g. 32K + ~7K for each zlib
stream). As usual, EROFS ourperforms similar approaches too.

Alternatively, DEFLATE could still be used for some specific files
since EROFS supports multiple compression algorithms in one image.

Pull erofs updates from Gao Xiang:
"No outstanding new feature for this cycle.

Most of these commits are decompression cleanups which are part of the
ongoing development for subpage/folio compression support as well as
xattr cleanups for the upcoming xattr bloom filter optimization [1].

In addition, there are bugfixes to address some corner cases of
compressed images due to global data de-duplication and arm64 16k
pages.

Summary:

- Fix rare I/O hang on deduplicated compressed images due to loop
hooked chains

- Fix compact compression layout of 16k blocks on arm64 devices

- Fix atomic context detection of async decompression

- Decompression/Xattr code cleanups"
