Sometimes, the value from of some DMI scans has no meaning (e.g. when
`op` is read). Such values should not be decoded. To make the dumps more
consistent, `<no decoding available>` is printed when there is no
decoding for a register.

By definition in `target/target.h`, `coreid` is not a unique identifier
of a target -- it can be the same for targets on different TAPs.

This patch replaces ~(typeof(watchpoint->mask))0 with
WATCHPOINT_IGNORE_DATA_VALUE_MASK. This improves
readability and moves the RISCV target in line with
other targets.

Depending on configuration, the existing implementation of watchpoints is
rather inefficient for certain scenarios. Consider HW that:
1. triggers 0-3 can be used as instruction breakpoints
2. triggers 4-7 can be used as data breakpoints (watchpoints)
3. NAPOT triggers are not supported.
Now, consider that we have a pending watchpoint. And we perform a "step"
operation. According to the current implementation:
* OpenOCD will disable watchpoints
* Perform a single-step
* Will try to restore the original watchpoints. It will need 12 attempts
to find a suitable trigger: (8 attempts to try NAPOT, and another 4 to try
GE+LE).
This patch introduces a dedicated cache for requests to triggers. It
significantly speeds things up, since we cache failed attempts and no
additional interactions with HW is necessary.

Otherwise it won't compile for me. Not sure why that doesn't affect the
automated builds.

Since DPC is WARL (same rules as MEPC according to
the specification), it is possible that
writes to it won't result in the exact value present.
Therefore, writes to it shouldn't be cached, same as
with other WARL registers.

Targets "esp32c2" and "esp32c3" should not be mentioned in the doc
under "target types" because these are not standalone OpenOCD
targets.
They are merely a set of .cfg files which use the generic
"riscv" target.

Now:
1) If mmu is disabled, virt2phys succeeded and returns physical address
2) If mmu is enbaled, but translation fails, read/write_memory fails

This incorrect extra call has been removed in upstream code already
in March 2022, see https://review.openocd.org/c/openocd/+/6836 .
Remove it from riscv-openocd as well.

Upstream has a checkpatch failure here. I had fixed it because I didn't
know how else to properly get around it back then. Reintroduce the
problem. Now this file is identical to upstream.
