Using up_textheap_memalign to allocate memory if arch support textheap

The default system heap does not support execution permissions,
so up_textheap_memalign allocation is required.

SiFive document: "ECC Error Handling Guide" states:
"Any SRAM block or cache memory containing ECC functionality needs to be
initialized prior to use. ECC will correct defective bits based on memory
contents, so if memory is not first initialized to a known state, then ECC
will not operate as expected. It is recommended to use a DMA, if available,
to write the entire SRAM or cache to zeros prior to enabling ECC reporting.
If no DMA is present, use store instructions issued from the processor."
Clean the cache at this early stage so no ECC errors will be flooding later.

When I try to set priorities in certain programs, such as init_priority(HIGH_PRIORITY), I've noticed that during linking, there's no guarantee that the programs will be compiled in the sequence I've specified based on priority. This has led to some runtime errors in my program.
I realized that in the ld file, when initializing dynamic arrays, there's no assurance of initializing init_array.* before init_array. This has resulted in runtime errors in the program. Consequently, I've rearranged the init_array.* in the ld file of NuttX to be placed before init_array and added a SORT operation to init_array.* to ensure accurate initialization based on priorities during linking.
Summary:
- I noticed that device discovery for virtio-mmio devices does not
work without bus=virtio-mmio-bus.x option. Without this option,
qemu assigns the virtio device into the virtio-mmio space
in reverse order automatically.
- To fix this issue, we must specify the correct numbers for the
target machines. (i.e. arm32/64->32, rv32/64->8)
Impact:
- None
Testing:
- Tested with qemu-7.2.4

Adds a platform specific implementation for tickless schedular operation. This includes:
- Tickless operation for vexriscv cores.
- Tickless operation for vexriscv-smp cores.
- Ticked operation for vexriscv-smp cores.
Ticked operation for vexriscv core has been refactored.
Additional default configuration added to demonstrate operation.
Both tickless and ticked options use Litex timer0 for scheduling intervals. This is significantly faster than interfaceing with the risc-v mtimer through opensbi.
Adding the CONFIG_ARCH_PERF_EVENTS configuration to enable
hardware performance counting，solve the problem that some platform
hardware counting support is not perfect, you can choose to use
software interface.
This is configured using CONFIG_ARCH_PERF_EVENTS, so weak_functions
are removed to prevent confusion
To use hardware performance counting, must:
1. Configure CONFIG_ARCH_PERF_EVENTS, default selection
2. Call up_perf_init for initialization

Changes the executable type built against the `make export` target fully linked by default. This greatly improves performance when loading applications, as relocations no longer need to be processed.
This also removes kconfig warning:

Adds a driver for an FPGA fabric / CoreSPI implementation.
Supports multiple instances, assuming they reside in some base address,
offsettable by a constant value.
This incorporates an fpga i2c driver into the existing i2c driver.
This fpga i2c works almost 100% as the MSS i2c, but the difference
is that the fpga driver terminates all transactions with a stop
sent -interrupt. That needs to be handled.
Fpga clock source is also different, act accordingly.
SEC2TICK(10) is an overkill to any app, use just one second instead.
modifyreg32s are simplified as well, no need to clear and set
as set is enough.

Instead of using Espressif's emulated NVS to save Wi-Fi data, use
`wapi`s wireless configure initialization mechanism for saving
Wi-Fi data. It 1) avoids creating a specific storage partition
just to save Wi-Fi data (ESP32-C3's storage partition is used
instead); 2) avoids initialization problems of the emulated NVS
when SMP is enabled (the Wi-Fi driver tries to initialize it before
the actual partition is initialized); and 3) enables reconnecting
using `wapi reconnect` command and connect the device automatically
on bringup if `CONFIG_NETUTILS_NETINIT` is selected.
Run:
$ ./tools/refresh.sh --silent --defaults all
It will report that CONFIG_START_DATE and/or CONFIG_START_MONTH
are using invalid value starting with 0, so 03 should be 3, and so
on.
I noticed sometimes once config changed, it will not launch to shell,
maybe due to
K210 is a 64-bit platform and without misaligned memory access support.
This patch may fix this problem, it will not introduce new issues at least.

This is a workaround commit to temporarily reduce the flash usage of

and this issue cannot be reproduced in the local environment,
so I temporarily turn off related optimizations to save flash size.
