In the original implementation of `sbi_strcpy` and `sbi_strncpy`, if the
destination buffer (`dest`) was longer than the source string (`src`),
the functions did not ensure that the remaining bytes in `dest` were
properly null-terminated. This could result in garbage data being
present in the destination buffer after the copy operation, as the
functions only copied characters from `src` without explicitly
terminating `dest`.

- Completed TODO in `system_opcode_insn` to ensure CSR read/write
instruction handling.
- Refactored to use new macros `GET_RS1_NUM` and `GET_CSR_NUM`.
- Updated `GET_RM` macro and replaced hardcoded funct3 values with
constants (`CSRRW`, `CSRRS`, `CSRRC`, etc.).
- Removed redundant `GET_RM` from `riscv_fp.h`.
- Improved validation and error handling for CSR instructions.
This patch enhances the clarity and correctness of CSR handling
in `system_opcode_insn`.

This patch introduces a new math test suite to the SBI unit
tests. The changes include:
* Updating lib/sbi/tests/objects.mk to include
math_test_suite and sbi_math_test.o.
* Adding a new file lib/sbi/tests/sbi_math_test.c which
contains tests for log2roundup function using various cases.
The addition of this test suite ensures that mathematical
functions are verified and work as expected.

This patch improves the readability of the SBI unit test
output by adding color-coded status messages.
Adding ANSI color codes for green (pass) and red (fail)
in sbi_unit_test.c.
Now, the test results will be displayed in green for passed
tests and red for failed tests, making it easier to quickly
distinguish between them.

This commit adds a new GitHub Actions workflow for repository
lockdown. The workflow triggers when a pull request is opened, and it
notifies the contributor to use the OpenSBI mailing list for patch
reviews.
Additionally, the .gitignore file is updated to include the .github
directory.

The t3 register stores the address of _load_end. If relocation is not
required, it is unnecessary to calculate the address of _load_end.
This can reduce the operation time of two instructions.
