Refactored eviction mechanism works as follows:
- eviction is needed only if
total size of cache binaries + size of the new binary exceed cache limit
- single evition call removes files with a summed size of 1/3 of the cache limit
- if new binary can not fit in the cache size limit
even after eviction, it will not be saved
- cache limit applies only to
files in cache directory with .cl_cache/.l0_cache extension.
Only these files are counted and only these files are removed

- set monitor fence dispatch for all cases task count post sync operation
- stand alone flush task count will not happen when already flushed and so
monitor fence
- monitor fence then must be dispatched together with task count post sync

What's changed:
- Add early return when open existing config
fails due to different error than `ERROR_FILE_NOT_FOUND`
- Swich `ReadFileEx` to `ReadFile`
- Add `SetFilePointer` to make sure we're reading
from the beginning of the file
- Pass `overlapped` to `WriteFile` to make sure
we're writing from the beginning of the file

- For calculating number of threads per workgroup, for SIMD 1, return
local work size (each software thread should be mapped into a whole hardware
thread).
- Correct logic of calculating space for per thread data for SIMD 1.
- Minor: unit tests refactor.
- Corrected naming.

CmdList can be released before Event. In this case, GfxAllocation
destruction must be deferred.

config.file should not be created manually by the user.
In a scenaro when the user manually creates an empty config.file,
then reading data from this file ends with failure,
because the file is empty.
Such scenario completely freezes the cache creation
until the user manually deletes the empty config file.
This patch fixes such freeze by automatically deleting config
if read fails with ERROR_HANDLE_EOF error.
Patch applies to windows only.

In L0 its not possible to track objects relations. For example CmdList
may be removed before Event.
In such case, Event needs to safely skip unregister call, without
accessing CmdList/CmdQueue object.

So far, there is a separate page allocated for each kernel's ISA within
`KernelImmutableData::initialize()`. Apparently the ISA blocks are often
much smaller than a 64k page, which leads to poor memory utilization and
was even observed to cause the device OOM error if a single module has
several keys.
Improve the situation by reusing the parent allocation (owned by the
module instance) for modules, which kernel ISAs can fit together within
a single 64k page. This improves the memory utilization on a single
module level.

Changes:
- replaced registry keys with environment variables
for cl_cache in OCL
- added compiler cache helpers
- implemented support for new env vars on Windows
- added tests
New env vars mechanism works as follows:
If `PERSISTENT_CACHE` is set,
driver checks if `NEO_CACHE_DIR` is set.
If `NEO_CACHE_DIR` is not set,
driver uses `%LocalAppData%\NEO\neo_compiler_cache`
as `cl_cache` destination folder.
If `NEO_CACHE_DIR` is not set and `%LocalAppData%`
path could not be obtained,
compiler cache is disabled.
In the current Windows implementation,
special characters in the folder path are not supported.
