Add safety checks to validate precision of unsigned types.
These validations are used to justify that no security issues
exist in NvGPU driver due to CERT-C INT34-C and INT35-C
violations.
These are done early in the driver probe to ensure that
code violating CERT-C INT34-C and INT35-C rules is not run
before these checks.

Do some doxygen cleanup for the whitelisting macros:
- Previously doxygen documentation was being generated for the no-op
whitelisting macros. Enable the NV_IS_COVERITY define in the
doxygen build. This generates doxygen documentation for the actual
whitelisting macros.
- Create a doxygen group for the whitelisting macros. This adds
additional documentation for the whitelisting macros.
- Add doxygen line breaks

Add macros for whitelisting coverity violations. These macros use pragma
directives. The pragma directives and whitelisting macros are only
enabled when a coverity scan is being run.
The whitelisting macros have been added to a new header called
static_analysis.h. The contents of safe_ops.h (CERT C safe ops) have
been moved into static_analysis.h because this will be the new header
for static analysis related macros/defines/etc.
