aa0fd027fc fs: Add support for mount flags
The flags field has been added to fs_mount_t structure, accompanied
with two new flags:
  FS_MOUNT_FLAG_READ_ONLY -- mount fs as read only
  FS_MOUNT_FLAG_NO_FORMAT -- do not format volume when system not found

Code supporting the flags has been added to FS layer and drivers for
LittleFS and FAT FS.

e43ec70d4f subsys/fs: Make FAT FS write support optional
The commit adds FS_FATFS_READ_ONLY Kconfig option; the option, when
selected, excludes write supporting code within ELM FAT driver.

When write support to FAT FS volumes is not desired, this option may be
selected to slightly reduce code size.

397b2a71fa net: lwm2m: Add a callback to notify socket errors to engine users
Currently, when socket errors occur during receive, the LwM2M engine
restarts the state machine and registers again to the server. While this
works in simple use case (only RD client socket open), it's not a valid
approach when more sockets are open (FW update socket).

Fix this by introducing socket fault callback, which is registered by
the LwM2M engine users. This way, a proper socket owner is notified on
error and can pertake appropriate action.

For RD socket errors the behaviour remains the same - the state machine
is reset and the client registers again to the server. For FW update
socket, handle the error by reopening the socket and retransmitting the
last request. This allows to resume the download from the point the
error occured, w/o a need to start from scratch.

d2a72273b7 x86: add support for common page tables
We provide an option for low-memory systems to use a single set
of page tables for all threads. This is only supported if
KPTI and SMP are disabled. This configuration saves a considerable
amount of RAM, especially if multiple memory domains are used,
at a cost of context switching overhead.

Some caching techniques are used to reduce the amount of context
switch updates; the page tables aren't updated if switching to
a supervisor thread, and the page table configuration of the last
user thread switched in is cached.

b8242bff64 x86: move page tables to the memory domain level
- z_x86_userspace_enter() for both 32-bit and 64-bit now
  call into C code to clear the stack buffer and set the
  US bits in the page tables for the memory range.

- Page tables are now associated with memory domains,
  instead of having separate page tables per thread.
  A spinlock protects write access to these page tables,
  and read/write access to the list of active page
  tables.

- arch_mem_domain_init() implemented, allocating and
  copying page tables from the boot page tables.

- struct arch_mem_domain defined for x86. It has
  a page table link and also a list node for iterating
  over them.

d8912fe895 net: lwm2m: Remove handle_separate_response flag
It shouldn't be optional to handle separate response, as it's a
mandatory requirement according to the RFC7252:

"The protocol leaves the decision whether to
 piggyback a response or not (i.e., send a separate response) to

Therefore, remove the flag as separate responses are handled now
