Added a flash driver for the STM32G4 series. The primary change here is
the addition of stm32g4xxx_flash.c. This file uses the STM32L4 flash
driver as a template. The primary difference is the accounting for dual
banks with different page sizes.
Fixed error while building b-g474e-dpow1/buckboost. It was possible (technically) to have page be used uninitialzied. Changing the if statement to default to using a flash_page_size == 2048 fixes this issue.
`g_iob_sem.semcount` is both manually changed in iob source code and api
nxsem_xxx.
nxsem related API uses critical_section to ensure sem value is modified
correctly. If iob using spin lock and modify sem value in the same time,
it's not safe.
This PR revert the spin lock change and uses critical section to align
with what nxsem uses.
This patch fixes the PR Labeler, such that PRs with modified files in `include/*.h` and `include/nuttx/*.h` are labeled as "Area: OS Components". Previously the PR Labeler ignores files like `include/nuttx/elf.h`, which causes Build Jobs to be skipped incorrectly.
In armv8m the FPSCR[18:16] LTPSIZE field must be set to 0b100 for
"Tail predication not applied" as it's reset value.

reason:
We can utilize percpu storage to hold information about the
current running task. If we intend to implement this feature, we would
need to define two macros that help us manage this percpu information
effectively.
up_this_task: This macro is designed to read the contents of the percpu
register to retrieve information about the current
running task.This allows us to quickly access
task-specific data without having to disable interrupts,
access global variables and obtain the current cpu index.
up_update_task: This macro is responsible for updating the contents of
the percpu register.It is typically called during
initialization or when a context switch occurs to ensure
that the percpu register reflects the information of the
newly running task.
