Compiler and runtime support for global allocation metadata
On the compiler side, enumerate used global allocations, assign each used
global allocation a unique ID, and record the mapping in an OpString
in the result SPIR-V code. The ID is the index of the metadata
for the global allocation.
On the runtime side, added a new RSoVBuffer for metadata, and with code
marshaling them for the kernel according to the mapping reported by the
compiler. SPIRIT is linked against the driver for extracting metadata
out of the SPIR-V module.
Added a new testcase for global allocation metadata in RSoVTest.

Rename unused fields of RS base object handle in 64-bits
Fields other than the first one (p) in RS_BASE_OBJECT are set in some
part of existing RS runtime, but is not used at all. However, removing
them is not desirable as size of RS_BASE_OBJECT is really part of the
ABI and thus if we change it, we are creating a new ABI variant here,
which is not always desirable.
For example, consider a library that contains compiled scripts and
assuming we pass allocation handles between the library and other
user codes, changes to handle size only in user code would break the
compatibility on things like array of rs_allocations.
Thus, to keep ABI compatibility the unused fields r, v1, v2 are renamed.
Also they are now assigned zero consistently. These field however are
not copied consistently in the current runtime, and are not expected
so anyways.

Move Vulkan buffer details out of RSoVAllocation
Bug: 30964317
Small refactoring of RSoVAllocation class. The Vulkan-specific
implementation of buffers now goes to RSoVBuffer.

Rewrite rs2spirv using spirit
Bug: 30964317
Rewrote the wrapper generation and builtin/runtime function
translation passes in rs2spirv using spirit.
Also added support for about a dozen more floating-point builtin
math functions.
Added support for new-style root kernel with lit test. Added check
for old-style kernels with lit test. Updated existing lit tests
since generated code are slightly different, mostly on temp names.
Added SPIR-V validation to all lit tests.
Updated the RSoV driver to work with the new spirit-based compiler.
The entry point is now named entry_<kernel name>.
Fixed an issue with multi-input kernel, so that the type count is
correctly set.
Minor cleanup to destroy descriptor sets after a kernel launch
and to remove an outdated comment.
Test: lit tests and RSoVTest

Runtime support for mapping kernels with multiple input allocations
Updated RSoV runtime to set Vulkan GLSL bindings for kernels with more
than one input allocations at kernel launch time.
Added a RSoVTest test case based on foreach_multi of RSTest.

Fallback to CPU execution if RSoV compilation fails
Bug: 30964317
With a few additional changes:
* Cleaned up the RSoV script initialization code to get rid of
memory leaks;
* Updated the RSoVAllocation destructor to destroy the buffer but
not the uninitialized image.
* Updated allocation initialization code to correctly calculate
allocation size when rows are not aligned to the default minimum
alignment (16 bytes).
* Added a utility function to check if a script is completely backed
by CPU, and updated the CPU context lookup callback function to
use this utility to correctly return a CPU driver-specific script
for a HAL script.
Test: RSoVTest and RsTest

Multiple argument support for the RSoV compiler
Generated SPIR-V wrapper now contains localized decorations and buffer
declarations for kernel arguments. Also updated kernel wrapper generation
so that now the boilerplate code loads all input buffers as well.
Renumbered GLSL binding for allocations in the runtime accordingly.
Added a LIT test.
Test: RSoV lit tests, RSoVTest

Initial multi-kernel support
This change adds multi-kernel support, with localized kernel function
types, argument types and OpEntryPoints. Also emit type and metadata
for each kernel. OpEntryPoints now have the string literals of RS
kernel names.
Some SPIR-V names are still shared, notably the global_invocation_id. This
doesn't seem to affect correctness per our current tests.
On the device side, the RSoV driver has been updated to use actual kernel
names instead of hardcoded "main".
Also added testcases in both LIT and RSoVTest.
Test: RSoV LIT Tests, RSoVTest on angler

Initial driver for RSoV (RenderScript over Vulkan/SPIR-V)
Bug: 30964317
Supports the following:
* Allocations of 32-bit integers and floating point numbers and vectors
* Single-input single-output kernels
* Co-existence of RSoV scripts and CPU intrinsics
Added default .clang-format for driver code using Google C++ code style.
The RSoV driver is loaded, if and only if the property debug.rs.rsov is
set to non-zero.
Test: RSTest and CTS with debug.rs.rsov set to 0; and RSoVTest with
debug.rs.rsov set to 1.
