trace-events: remove the remaining vcpu trace events

While these are all in helper functions being designated vcpu events
complicates the removal of the dynamic vcpu state code. TCG plugins
allow you to instrument vcpu_[init|exit|idle].

We rename cpu_reset and make it a normal trace point.

trace-events: Fix attribution of trace points to source

Some trace points are attributed to the wrong source file. Happens
when we neglect to update trace-events for code motion, or add events
in the wrong place, or misspell the file name.

Clean up with help of scripts/cleanup-trace-events.pl. Funnies
requiring manual post-processing:

* accel/tcg/cputlb.c trace points are in trace-events.

* block.c and blockdev.c trace points are in block/trace-events.

* hw/block/nvme.c uses the preprocessor to hide its trace point use
from cleanup-trace-events.pl.

* hw/tpm/tpm_spapr.c uses pseudo trace point tpm_spapr_show_buffer to
guard debug code.

* include/hw/xen/xen_common.h trace points are in hw/xen/trace-events.

* linux-user/trace-events abbreviates a tedious list of filenames to
*/signal.c.

* net/colo-compare and net/filter-rewriter.c use pseudo trace points
colo_compare_miscompare and colo_filter_rewriter_debug to guard
debug code.

The memory_region_tb_read tracepoint is unreachable, since notdirty
is supposed to apply only to writes. The memory_region_tb_write
tracepoint is mis-named, because notdirty is not only used for TB
invalidation. It is also used for e.g. VGA RAM updates and migration.

Replace memory_region_tb_write with memory_notdirty_write_access,
and place it in memory_notdirty_write_prepare where it can catch
all of the instances. Add memory_notdirty_set_dirty to log when
we no longer intercept writes to a page.
