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.

`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>, ..., }`

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.

The USB control transfer can be executed without any data.
The libusb API libusb_control_transfer() can thus be called with
zero 'size', thus returning zero byte transferred when succeed.
The OpenOCD API jtag_libusb_control_transfer() returns zero either
in case of transfer error and in case of libusb_control_transfer()
returning zero, making impossible discriminating the two cases.
Extend jtag_libusb_control_transfer() with separate return value
for error code and explicit parameter's pointer for transferred
bytes.
Make the transferred pointer optional, as many callers do not
properly handle the returned value.
Use 'int' type pointer for transferred, instead of the 'uint16_t'
that would have matched the type of 'size'. This can simplify the
caller's code by using a single 'int transferred' variable shared
with other jtag_libusb_bulk_read|write, while keeping possible the
comparison int vs uint16_t without cast.
This change is inspired from commit d612baacaa
("jtag_libusb_bulk_read|write: return error code instead of size")
