The two instances of RzReg were assigned to the same pointer in core.
This had several disadvantages, in particular:
* Both debug and analysis supply reg profiles, which might not be
compatible. Which one was used in practice depended on which eval
vars were set in which order.
* Emulation, in particular esil-based analysis, could leak into the
debuggee.
Now they are fully independent.
* Logic for getting a register by role or name, whichever matches, moved
to RzReg (rz_reg_get_by_role_or_name)
* Removed rz_debug_reg_err() because it's unnecessary
* Added rz_core_reg_getv_by_role_or_name() and
rz_core_reg_aetv_by_role_or_name() to replace rz_debug_reg_get() for
for usage whenever it is not debug-specific.
* Add function to check if a register is a system register
* Only checks for ARM64 system registers as of now
* Check for system registers in ARM64 when printing registers using "dr"
* Does not completely remove the unnecessary register, but removes a
huge number of useless registers printed by "dr"
* Rename `RZ_REG_TYPE_ALL` to `RZ_REG_TYPE_ANY`
* ADd register types for "sys" and "pauth": `RZ_REG_TYPE_SYS` and
`RZ_REG_TYPE_PAUTH` respectively
* Remove `rz_reg_is_system_reg`
* Add `sys` and `pauth` register profiles
* Update debug tests to account for new arenas and register profiles
* REplace "pauth" with "sec" reg profile
* Update integration tests to account for new register profiles: `sys`, `sec`
* Fix regression showing threads `rip` for `dpt` on Windows
* Improve `dpt` output
* Consider flags too when printing thread address
* Improve `RzCoreBind->getNameDelta` to use realname if `flags->realnames` is true
* Fix negative offsets
* Fix flagspace selection side-effects after calling `rz_core_bin_apply()` APIs
* Fix wrong register profile after attaching to a process with `dpa`
* Fix wrong base address when opening a process memory
* Fix wrong register profile after opening a process memory
* Implement `rz_debug_reg_profile_sync()`
* Fix diff tests
* Move rz_debug_reg_list from RzDebug to RzCore and directly use rz_cons_printf
* rz_reg_get_list returns always the same list, so make it const RzList *
