When a target in an SMP group is unavailable, the gdb layer might get an
event for a different target in that SMP group, but not one that is the
primary target for that gdb connection. So propagate events if they're
for any of the targets in the SMP group, not just if it's for the first
one in that group.

Exit early if conditions aren't satisfied, instead of putting the core
code inside an if().
Also return ERROR_FAIL if conditions are satisfied but no matching
registers were found.

Move `examine_attempted` flag to target struct to make it target specific.
`Info` messages for retry and `Error` messages for failure added.

If it fails, then pass that failure on. If it's simply not implemented,
then we can fall through and try target_get_gdb_reg_list_noread().
This difference matters when the target representing the current
hwthread is unavailable, but the target that is linked to the gdb
connection is available. In that case we want the operation to return an
error to gdb, instead of reading the register from the target that is
available.

When gdb requests to step an unavailable target, report success. When
the target becomes available, the step can complete.

Extend riscv set_ebreak* commands.
Now it can be called without args to print current value.
riscv_ebreak* flags are moved to riscv_info struct.

`riscv_debug_reg_to_s()` can be used to decode register value. If the
pointer to buffer is `NULL` it does not print anything, just returns the
length of the string.
The format is:
`<register_value> { <field_name>=<field_value_name or field_value>, ..., }`
e.g:
`0x400382 { version=2, ... ndmresetpending=false, }`
`0x321009 { regno=0x1009, ... cmdtype=0, }`

When the target isn't halted, simply return an error. This used to be
purely internal code so an assert was appropriate. Now after some
refactoring and with unavailable harts you could get here when the hart
is unavailable. In that case the right thing is simply to return an
error message.

Presently, we only look at the Part Number field of the CPUID, and
completely ignore the Implmentor field, simply assuming it to be ARM.
Parts have since been found, with different implementors, that use
overlapping part numbers, causing detection to fail.
Expand the "part number" field to be a full implementor+part number,
excluding the revision/patch fields, to make checking more reliable.

This also fixes a bug when, after `examine` completion, the target still
has `unknown` status. To reproduce this one spike, it is enough to do
the following:
---
// make sure spike harts are halted
openocd ... -c init -c 'echo "[targets]"'
---
this behavior is quite dangerous and leads to segfaults in some cases

This patch improves the following issues:
1. Makes it compatible with targets with progbufsize == 1.
2. Although exceptions don’t update any registers, but do end execution
of the progbuf. This will make fence rw, rw impossible to execute.

The motivation for this refactor is to fixup error handling for some
corner cases. These functions attempt to cache S0 register and only then
perform a bunch of extra checks to figure out if the requested register
is valid one in this context. The problem is that there are few corner
cases when _*progbuf functions could receive a GPR as an input. For
example, an abstract read could fail (for whatever reason) leading to
infinite recursion:
````
save S0 -> read S0 -> save S0 -> read S0 -> ...
```
The case described above could be fixed by adding extra sanitity checks,
however I decided to make these functions more modular since I find
self-contained functions easier to read.
