ARM: rename "arm9tdmi vector_catch" to "arm9 ..."

And update doc accordingly.  That EmbeddedICE register was
introduced for ARM9TDMI and then carried forward into most
new chips that use EmbeddedICE.

Such cores include the ARM920T, ARM926EJ-S, and ARM966.

For historical reasons, one command shared by these cores starts
with the @command{arm9tdmi} prefix.
This is true even for ARM9E based processors, which implement the
ARMv5TE architecture instead of ARMv4T.

Vector Catch hardware provides a sort of dedicated breakpoint
for hardware events such as reset, interrupt, and abort.
