Alexey Bataev 15ab891e68 [OPENMP]Make lambda mapping follow reqs for PTR_AND_OBJ mapping.
Summary:
The base pointer for the lambda mapping must point to the lambda capture
placement and pointer must point to the captured variable itself. Patch
fixes this problem.

Alexey Bataev 9476ca7db9 [OPENMP][OFFLOADING]Change the lambda capturing flags.
Summary:
The previously used combination `PTR_AND_OBJ | PRIVATE` could be used
for mapping of some data in Fortran. Changed it to `PTR_AND_OBJ |
  LITERAL`.

Alexey Bataev e5369885dd [LIBOMPTARGET] Add support for mapping of lambda captures.
Summary:
Added support for correct mapping of variables captured by reference in
lambdas. That kind of mapping may appear only in target-executable
regions and must follow the original lambda or another lambda capture
for the same lambda.
The expected data: base address - the address of the lambda, begin
pointer - pointer to the address of the lambda capture, size - size of
the captured variable.
When OMP_TGT_MAPTYPE_PTR_AND_OBJ mapping type is seen in
target-executable region, the target address of the last processed item
is taken as the address of the original lambda `tgt_lambda_ptr`. Then,
the pointer to capture on the device is calculated like `tgt_lambda_ptr
+ (host_begin_pointer - host_begin_base)` and the target-based address
of the original variable (which host address is
`*(void**)begin_pointer`) is written to that pointer.

George Rokos a0da24683b [OpenMP][libomptarget] New map interface: remove translation code and ensure proper alignment of struct members
This patch removes the translation code since this functionality is now implemented in the compiler.
target_data_begin and target_data_end are also patched to handle some special cases that used to be
handled by the obsolete translation function, namely ensure proper alignment of struct members when
we have partially mapped structs. Mapping a struct from a higher address (i.e. not from its beginning)
can result in distortion of the alignment for some of its member fields. Padding restores the original
(proper) alignment.

Jonas Hahnfeld 2559fbdf08 [libomptarget] Move header files and CMake library definition
Future patches will add (private) header files in src/ that should
not be visible to plugins, so move the "public" ones to a new
include/ directory. This is still internal in a sense that the
contained files won't be installed for the user.
Similarly, the target agnostic offloading library should be built
directly in src/. The parent directory is responsible for finding
dependencies and including all subdirectories.
