[components][clock_time] Refactor time subsystem around clock_time (#11111)

[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][raspi3] select clock time for systimer

[bsp][hpm5300evk] Trim trailing blank line

[bsp][hpm5301evklite] Trim trailing blank line

[bsp][hpm5e00evk] Trim trailing blank line

[bsp][hpm6200evk] Trim trailing blank line

[bsp][hpm6300evk] Trim trailing blank line

[bsp][hpm6750evk] Trim trailing blank line

[bsp][hpm6750evk2] Trim trailing blank line

[bsp][hpm6750evkmini] Trim trailing blank line

[bsp][hpm6800evk] Trim trailing blank line

[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

[docs][clock_time] Update clock time subsystem documentation



Update device driver index to use correct page reference
Clarify upper layer responsibilities in architecture overview
Update README to describe POSIX/libc, Soft RTC, and device driver usage
Refine architecture diagram with improved layout and color scheme
Remove obsolete clock_timer.md file


[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

sdio: fix missing card status polling after CMD6 in eMMC DDR mode switch
fix[dfs_v1]: prevent vnode ref underflow and double release on close/fd release
feat[STM32][CAN]: drain RX FIFO frames in ISR with a bounded limit to reduce overruns

Add CAN_ISR_DRAIN_LIMIT (default 3) to cap ISR work
Drain multiple frames per RX0/RX1 interrupt to reduce FIFO FULL/OVERRUN

docs(can): improve dev_can.h docs for batched RX example
fix[STM32][RTC]: Compute tv_usec from SecondFraction/SubSeconds and skip during shift pending
Use the generic SecondFraction/SubSeconds formula when SSR/PRER are available.
If SHPF is present and a shift is pending, keep tv_usec at 0.
Platforms without SSR/PRER (e.g. F1) default to 0.
