1) OpenOCD has the capability to 'force' a register read from the
target. This functionality however silently breaks the register
cache: During 'get_reg force' or 'reg <name> force',
reg->type->get() is called which will silently overwrite
dirty items in the register cache, causing a loss of unwritten
register values. This patch fixes that by adding a flush
callback for registers, and by using it when it is needed.
2) The register write commands did not have the 'force' flag;
this was present for register read commands only.
This patch adds it.
3) This patch also introduces the flush_reg_cache command. It
flushes all registers and can optionally invalidates the register
cache after the flush.
For targets which implement the register cache should implement
the flush() callback in struct reg_arch_type.
This functionality is also useful for test purposes. Example:
- In RISC-V, some registers are WARL (write any read legal)
and this command allows to check this behavior.
We plan to implement the corresponding callback
in the RISC-V target.

this commit fixes a regression introduced in
ba8c1eef5a.
The regression was caused by removal of these lines:
```
- /* Register prefix: "csr_" or "custom_" */
- strcpy(name, reg_type);
- name[strlen(reg_type)] = '_';
```
causing all CSR names with custom names to be parsed as empty strings.
Add maskisr command support to Xtensa NX targets allowing masking
of interrupts during single stepping.

There was a conflict:
1. commit 2cd8ebf44d ("breakpoints: use 64-bit type for watchpoint mask
and value")
2. commit 0bf3373e80 ("target/breakpoints: Use 'unsigned int' for
length")
The second commit was created erlier, but merged later so the types of
`mask` and `value` became `uint32_t` in `watchpoint_add_internal()`.
This created a bug:
`WATCHPOINT_IGNORE_DATA_VALUE_MASK` is defined as `(~(uint64_t)0)`.
Truncation to uint32_t makes it so the comparisons with the constant
don't work.

Per current OpenOCD conventions, LOG_ERROR should not be printed
when ERROR_COMMAND_SYNTAX_ERROR is returned. OpenOCD will print
the command syntax to the user on its own.
In multi-target SoC not all the targets are running simultaneously
and some target could be powered off or kept under reset.
Commit 4892e32294 ("target/cortex_m: allow poll quickly get out
of TARGET_RESET state") does not considers the case of a target
that is kept in reset and expects the target to change state from
TARGET_RESET immediately.
This causes OpenOCD to log continuously:
Info : [stm32mp15x.cm4] external reset detected
Info : [stm32mp15x.cm4] external reset detected
Info : [stm32mp15x.cm4] external reset detected
Read again dhcsr to detect the 'stable' reset status and quit,
waiting for next poll to re-check the target's status.

Existing flags: 'enable_virtual' and 'enable_virt2phys' were
replaced with explicit translation drivers. Motivation:
(1) Having 'enable_virtual' and 'enable_virt2phys' flags set simultaneously
may cause double address translation which is unacceptable
(2) Flags were global for all targets which is wrong too
