Add codeowners for bundler and wrapper tools (intel#2845)

Since these tools are placed in clang/ directory, the automation
requests review from clang frontend code owners, this is not correct. Add
proper code owners for these tools.

…te (intel#2816)

This patch

adds support for template parameter on [[intel::max_global_work_dim)]] attribute

splits test/SemaSYCL/intel-max-global-work-dim.cpp to separate files for
host compilation (test/SemaSYCL/intel-max-global-work-dim.cpp-host.cpp) and
device compilation (test/SemaSYCL/intel-max-global-work-dim.cpp-device.cpp)

updates sema/codegen tests with mock headers on device.

uses existing function "sema::addIntelSYCLSingleArgFunctionAttr" from
other single argument function attributes such as num_simd_work_items 
and intel_reqd_sub_group_size to avoid source codes duplication and 
reuse for the template parameter support.

addresses special diagnostics in case the value of ‘max_global_work_dim’ 
attribute equals to  0, we shall ensure that if max_work_group_size and 
reqd_work_group_size attributes exist, they hold equal values (1, 1, 1).

additionally updates sema/codegen tests for "reqd-sub-group-size" and 
"num-simd-work-items" attributes with mock headers.

[SYCL][NFC] Fix static code analysis concerns (intel#2822)

Found via a static-analysis tool:

Inside VisitTemplateTemplateArgument()

    TemplateDecl *TD = TA.getAsTemplate().getAsTemplateDecl(); --->Pointer 'TD' returned from call to function 'getAsTemplateDecl' may be NULL

    TemplateParameterList *TemplateParams = TD->getTemplateParameters(); --> will be dereferenced here

This patch fixes null pointer dereference issues in SemaSYCL.cpp file by adding assert().
