[SYCL] Use device code cache when building kernel bundles (#4724)

The persistent device code cache, when enabled, is not used when
building the underlying native program in a kernel bundle. These changes
unify cache lookup with a fallback to program creation from
ProgramManager::getBuiltPIProgram with the program creation in
ProgramManager::build, ensuring that the latter also uses cached device
code. Likewise, ProgramManager::build will write the device code to the
persistent cache if it was not there already.

[ESIMD] Refactor esimd intrinsic mapping to BE intrinsics. (#4720)

* [ESIMD] Refactor esimd intrinsic mapping to BE intrinsics.

This patch
- makes names and parameter lists of __esimd* intrinsics match their
  @llvm.genx counterparts. The benefits are:
  * this removes the extra logical translation layer between __esimd* and
    @llvm.genx thus simplifying overall user-level esimd intrinsic translation
  * allows to reuse lots of functionality between SLM and surface memory
    accesses
- moves some of the translations and argument setting (like accessor field to
  surface index, setting scale) from LowerESIMD.cpp to the ESIMD headers, which
  simplifies code base.
- for all memory intrinsics moves host and device implementations to the same
  intrinsic function prototype separating them via __SYCL_DEVICE_ONLY__ macro
  thus avoiding duplication of the prototypes
- removes certain redundant __esimd* intrinsics, such as SLM memory accesses
  (which are normal surface accesses with special surface index 254), and
  __esimd_reduced_fmax,... which have the same functionality as usual fmax,...

This is also a preparatory step for fixing SLM memory accesses (revising vector
lengths, element types restirictions)

[ESIMD] Fix build error showed with disabled asserts (#4733)

Surprisingly Instruction->getNameOrAsOperand() is not defined when
asserts are disabled. Replaced that method usage with getName() method.

[SYCL] Detect changes in sycl headers (#4723)

This is follow up for #4710

When a sub-directory of the DEPENDS directories is modified the change is not
detected by CMake. The change adds a full list of files in the sub-directory to
DEPENDS to detect the change. file(GLOBE_RECURSE) is used with
CONFIGURE_DEPENDS option to rerun configure step if a new entry is added to
the directory structure.
Restore version.hpp in source directory as it is used to build SYCL
library.

Removing a header file is the only case when change is not propagated to
the build and install directory. This problem existed before the change and
TODO was left to fix it in the future.
