It is a stack high-point for some compression strategies and has an easy
fix. This moves the normalized count into the entropy workspace.

[bug-fix] Make simple single-pass functions ignore advanced parameters
...
The simple compression functions are intended to ignore the advanced
parameters, but they were accidentally using them. All the
`ZSTD_parameters` were set correctly, but any extra parameters were
used as-is. E.g. `ZSTD_c_format`.
This PR makes all the simple single-pass functions listed below ignore
the advanced parameters, as intended.
* `ZSTD_compressCCtx()`
* `ZSTD_compress_usingDict()`
* `ZSTD_compress_usingCDict()`
* `ZSTD_compress_advanced()`
* `ZSTD_compress_usingCDict_advanced()`
It also adds a test case that ensures that each of these functions
ignore the advanced parameters.

[lib] Set appliedParams.compressionLevel correctly
...
Forward the correct compressionLevel to the appliedParams in all cases.
It was already correct for the advanced API, so only the old single-pass
functions needed to be fixed.
This compression level is unused by the library, but is set so that the
tracing framework can consume it.

[trace] Keep track of a uint64_t tracing context
...
The most common information that you want to track between begin() and
end() is the timestamp of the begin function, so you can measure the
duration of the (de)compression call. Allow the tracing library to put
this information inside the `ZSTD_TraceCtx`, so it doesn't need to keep
a global map in this case. If a single uint64_t is not enough, the
tracing library can return a unique identifier (like the context
pointer) instead, and use it as a key in a map.
This keeps the simple case simple.

Don't shrink window log in ZSTD_getCParams()

Treat ZSTD_getCParams() and ZSTD_adjustCParams() in the same way
we treat streaming compression. Choose parameters based on the
dictionary size + source size, and assume the source size is small
if unkown. But, don't shrink the window log down in
ZSTD_adjustCParams_internal().
