config files: Drop incorrect comments.
There are many "force an error till we get a good number" comments in
target/board files. This refers to the use-case where a config script
sets _CPUTAPID to 0xffffffff (which presumely gets overridden later):
if { [info exists CPUTAPID ] } {
set _CPUTAPID $CPUTAPID
} else {
# Force an error until we get a good number.
set _CPUTAPID 0xffffffff
}
However, the same comment was also copy-pasted in many files which do
_not_ set _CPUTAPID to 0xffffffff, where the comment doesn't make any
sense at all. Drop those comments. Also, add one missing comment, and
fix small whitespace and grammar issues.

stm32f1x: use async algorithm in flash programming routine
Let the target algorithm be running in the background and buffer data
continuously through a FIFO. This reduces or removes the effect of latency
because only a very small number of queue executions needs to be done per
buffer fill. Previously, the many repeated target state changes, register
accesses (really inefficient) and algorithm uploads caused the flash
programming to be latency bound in many cases. Now it should scale better
with increased throughput.

stm32f1x: use register base instead of register offset

registers. Add a note about that.

Split armv7m_run_algorithm into two pieces and use them to reimplement it.

target: add async algorithm entries to the target type
On supported targets, this may be used to start a long running algorithm in
the background so the target may be interacted with during execution and
later wait for its completion.
The most obvious use case is a double buffered flash algorithm that can
upload the next block of data while the algorithm is flashing the current.
