Make sure we set the gcov tool in a consistent way and avoid issues
where path is set as Path instead of a string.

Verify we have the coverage tool we want to use, otherwise we will end
up with many warnings and errors during coverage data collection.

In some cases genhtml incorrectly built reports from LCOV
coverage data using full path for some of the source files
and relative paths for other files.
This fix adds `--prefix` parameter to shorten paths explicitly
relative to the ZEPHYR_BASE directory.

Support lcov > 2.0 tool which has strict error checking and some new

Apply a workaround for an issue introduced with bc8b7dd
for code coverage collection at qemu_x86 when gcov data
was broken because of optimized out memcpy() in write_u64()
static inline function, so gcovr parser fails with
"gcovr.gcov_parser.NegativeHits: Got negative hit value
in gcov line 'branch 1 taken -1'".
Add gcovr command line option to ignore such errors (since v.6.0):
"--gcov-ignore-parse-errors=negative_hits.warn_once_per_file"

Do not break processing when incorrect coverage data are received.
Instead, report failures but still process valid data.
Include coverage processing status within twister retrun code.

When using twister to generate coverage with the coverage tool lcov,
allow using --coverage-formats to pick if you want lcov or html,
defaulting to both. Picking html will also use lcov, since that is
required for geninfo. This will allow callers to avoid the potentially
slow and disk intensive html reports if they only wanted the lcov info
file.

We do not want to use gcov from the SDK for native posix and unit tests,
instead we want the system gcov. Restore logic that determines that.

When using llvm we need to set the gcov-tool to "llvm-cov gcov" but
the lcov tool is incapable of passing arguments to the gcov-tool. i.e.
the following cannot work:
$ lcov --gcov-tool "llvm-cov gcov" ...
Instead, create a symlink to llvm-cov prefixed as `gcov` which by the
documentation of llvm-cov will alias to `llvm-cov gcov` subcommand.
