f08c4b823f freertos: Fix FPU ISR core pinning bug
This commit fixes a bug where if an unpinned task is interrupted by a level 1
ISR that users the FPU, the FPU usage will cause the interrupted task to
become pinned to the current core.

Note: This bug was already fixed in SMP FreeRTOS in commit
d6936177. This commit simply backports the fix to IDF FreeRTOS.

d1db2df316 components/bt: High level interrupt in bluetooth
components/os: Move ETS_T1_WDT_INUM, ETS_CACHEERR_INUM and ETS_DPORT_INUM to l5 interrupt

components/os: high level interrupt(5)

components/os: hli_api: meta queue: fix out of bounds access, check for overflow

components/os: hli: don't spill registers, instead save them to a separate region

Level 4 interrupt has a chance of preempting a window overflow or underflow exception.
Therefore it is not possible to use standard context save functions,
as the SP on entry to Level 4 interrupt may be invalid (e.g. in WindowUnderflow4).

Instead, mask window overflows and save the entire general purpose register file,
plus some of the special registers.
Then clear WindowStart, allowing the C handler to execute without spilling the old windows.
On exit from the interrupt handler, do everything in reverse.

components/bt: using high level interrupt in lc

components/os: Add DRAM_ATTR to avoid feature `Allow .bss segment placed in external memory`

components/bt: optimize code structure

components/os: Modify the BT assert process to adapt to coredump and HLI

components/os: Disable exception mode after saving special registers

To store some registers first, avoid stuck due to live lock after disabling exception mode

components/os: using dport instead of AHB in BT to fix live lock

components/bt: Fix hli queue send error

components/bt: Fix CI fail
