6be156bd4d plugins: remove qemu_plugin_id_t from qemu_plugin_vcpu_simple_cb_t 
Not used in all our plugins.
Future commits will remove qemu_plugin_vcpu_simple_cb_t completely, and
replace it with qemu_plugin_vcpu_udata_cb_t, so id information can be
passed using userdata if needed.

In our plugins, only tests/tcg/plugins/reset.c was using it.

71b424ca76 plugins: add missing docstrings to qemu-plugin.h 
This patch adds docstrings for typedefs and function declarations in
include/plugins/qemu-plugin.h that were previously missing. This
resolves inconsistencies in the docs, e.g., the description for
qemu_plugin_read_register() referring to qemu_plugin_register_flush_cb()
but code cache flush callbacks not being documented themselves.

3ebd871cbd plugins: add read-only property for registers 
Some registers should be marked as read-only from a plugin API
perspective, as writing to them via qemu_plugin_write_register has no
effect. This includes the program counter, and we expose this fact to
the plugins with this patch.

4f55cd7801 plugins: add PC diversion API function 
This patch adds a plugin API function that allows diverting the program
counter during execution. A potential use case for this functionality is
to skip over parts of the code, e.g., by hooking into a specific
instruction and setting the PC to the next instruction in the callback.

d16ffa4244 plugins: add flag to specify whether PC is rw 
In addition to the flags specifying whether general-purpose registers
are read-write (rw) during a plugin callback, we add an additional flag
explicitly stating whether the PC is writable. This is in preparation of
a patch that allows to explicitly set the PC to divert control flow from
within a plugin callback, which is currently not possible.

cab15547f1 plugins: move qemu-plugin.h to include/plugins/ 
This change has two benefits:
- ensure plugins can't include anything else from QEMU than plugins API
- when compiling a C++ module, solves the header conflict with iostream
  header that includes transitively the wrong ctype.h, which already
  exists in include/qemu.

By Hyrum's law, there was already one usage of other headers with mem
plugin, which has been eliminated in previous commit.
