* [components][clock_time] Refactor time subsystem around clock_time
Introduce the clock_time core with clock source/event separation, high-resolution scheduling, and boot-time helpers, plus clock_timer adapters for timer peripherals.
Remove legacy ktime/cputime/hwtimer implementations and migrate arch and BSP time paths to the new subsystem while keeping POSIX time integration functional.
Update drivers, Kconfig/SConscript wiring, documentation, and tests; add clock_time overview docs and align naming to clock_boottime/clock_hrtimer/clock_timer.
* [components][clock_time] Use BSP-provided clock timer frequency on riscv64
* [risc-v] Use runtime clock timer frequency for tick and delays
* [bsp] Add clock timer frequency hooks for riscv64 boards
* [bsp] Update Renesas RA driver doc clock_timer link
* [bsp] Sync zynqmp-r5-axu4ev rtconfig after config refresh
* [bsp][rk3500] Update rk3500 clock configuration
* [bsp][hpmicro] Add rt_hw_us_delay hook and update board delays
* [bsp][stm32l496-st-nucleo] enable clock_time for hwtimer sample in ci
* [bsp][hpmicro] Fix rtconfig include scope for hpm6750evk
Move rtconfig.h include outside the ENET_MULTIPLE_PORT guard for hpm6750evk and hpm6750evk2 so configuration macros are available regardless of ENET settings.

* [bsp][hpm6e00evk] Trim trailing blank line
* [bsp][nxp] switch lpc178x to gcc and remove mcx timer source
* [bsp][stm32] fix the CONFIG_RT_USING_CLOCK_TIME issue.
* [docs][clock_time] add clock time documentation

* [kernel][utest] Trim trailing space
* [clock_time] Fix hrtimer wrap handling
* [clock_time] fix the static rt_inline issue
* [clock_time] fix the rt_clock_hrtimer_control result issue[HUST CSE] Fix many abnormal symbols in annotations and format code2023-04-18T02:26:23Z7YZ782019212+7YZ7@users.noreply.github.com2023-04-18T02:26:23Zurn:sha1:501b22aabede2d4e179bfc47f3b75522e5933da4🐞 fix(components/drivers): fix cpu timer in multithreading (#7222)2023-04-13T08:00:19Zxqyjljxqyjlj@126.com2023-04-13T08:00:19Zurn:sha1:970c7c6f7a8b6e26e3254de5c9c0877b18fa0627
