[ARM] Update knowledge of bfd architectures

Commit c0c468d562649df0f695737262b6230b7a56a4bb updated bfd's knowledge
of Arm architectures to Armv5TEJ and later but missed the list of CPUs
recognized by objdump -d -m<cpu>.

.note.gnu.arm.ident related code is intentionally not updated as build
attributes are a better mechanism to express the ISA in a file. However
this patch adds tests for the existing code since no existing testcase
cover those codepaths. Since I've only ever managed for
bfd_arm_get_mach_from_notes () to have an effect by using objcopy on
a file with a note but no Arm build attribute, the tests make use of
both objcopy actions supported by run_dump_test which requires to have a
ld line as well.

Note that the CPU list in bfd/cpu-arm.c was simply copied over from
GAS' CPU list but sorted alphabetically as already done for existing
entries.

bfd/
	* cpu-arm.c (processors): Add processors known to GAS but missing here
	and reindent.
	(bfd_arm_update_notes): Add comment explaining why the list of
	architectures in the switch should not be updated.
	(architectures): Likewise.
