When generating syscall wrappers, call a tracing macro with the id,
name, and all parameters of the syscall as params when entering and
leaving the syscall. This can be disabled in certain call sites
by defining DISABLE_SYSCALL_TRACING which is useful for certain
tracing implementations which require syscalls themselves to work.
Notably some syscalls *cannot* be automatically traced this way and
headers where exclusions are set are in the gen_syscall.py as notracing.
Includes a systemview and test format implementation.
Tested with systemview, usb, and uart backends with the string
formatter using the tracing sample app.
Debugging the trace wrapper can be aided by setting the TRACE_DIAGNOSTIC
env var and rebuilding from scratch, a warning is issued for every
instance a syscall is traced.
Automatically generating a name mapping for SYSVIEW_Zephyr.txt is a
future item as is documenting how to capture and use the tracing data
generated.

New version of Systemview has Zephyr API description that did not match
what we had, align with what the tools provides and expand hooks to
support additional APIs. We now cover most kernel APIs.

The sysview module does not set an interrupt number when recording ISRs
using SEGGER SystemView. Added ISR numbers for Cortex-M based chips.

Enables optionally placing Segger RTT and SystemView data in the DTCM
linker section instead of the default data section. This is needed on
SoCs in the i.MX RT series that use cacheable external SDRAM to store
data.

This adds a Kconfig option for enabling post-mortem mode of SystemView.
This is useful for crashes that occur after a longer period of time.

Now that device_api attribute is unmodified at runtime, as well as all

Several reviewers agreed that DT_HAS_NODE_STATUS_OKAY(...) was an
undesirable API for the following reasons:
- it's inconsistent with the rest of the DT_NODE_HAS_FOO names
- DT_NODE_HAS_FOO_BAR_BAZ(node) was agreed upon as a shorthand
for macros which are equivalent to
DT_NODE_HAS_FOO(node) && DT_NODE_HAS_BAR(node) &&
- DT_NODE_HAS_BAZ(node), and DT_HAS_NODE_STATUS_OKAY is an odd duck
- DT_NODE_HAS_STATUS(..., okay) was viewed as more readable anyway
- it is seen as a somewhat aesthetically challenged name
Replace all users with DT_NODE_HAS_STATUS(..., okay), which is
semantically equivalent.
This is mostly done with sed, but a few remaining cases were done by
hand, along with whitespace, docs, and comment changes. These special
cases include the Nordic SOC static assert files.

Rename DT_HAS_NODE to DT_HAS_NODE_STATUS_OKAY so the semantics are
clear. As going forward DT_HAS_NODE will report if a NODE exists
regardless of its status.
