* Precompiled SPIR-V import support
Adds appropriate linkage and function declaration syntax
for SPIR-V functions that are declared, to be imported
from another SPIR-V module.
Unlike DXIL, stripping the Slang IR for a function down
to a declaration requires retaining a block of parameters,
as the function declaration must be emitted to SPIR-V
with the same parameters as a definition. Because that
thwarts the logic in Slang to tell the difference between
a declaration and definition, and explicit decoration is
introduced to explicitly mark functions which need to be
treated as declarations during emit phase.
Fixes #4992

* Use Offset instead of ConstOffset for GLSL function textureGatherOffset
This commit changes to use `Offset` option on OpImageGather instruction
when translating `textureGatherOffset` to SPIR-V code.
Interestingly GLSL allows the offset value to be a variable not
constant just for the function `textureGatherOffset` while all other
offset variants of texture sampling functions require the offset to be a
constant value.
From a few experiments, I found that the spirv-optimizer changes
`Offset` to `ConstOffset` if the offset is a compile-time value. I also
found that when the offset value is zero, it changes to `None` with no
offset value.

(#5415)
This commit changes the word "stdlib" or "standard library" to "core module" in the source code.
|
|
The directory name of `source/slang-stdlib` is changed to `source/slang-core-module`.
We will use the term "core module" instead of "standard library" from now on.

* Add documentation for buffer types
* address comments
* Update doc for LoadxAligned functions
Update the doc for all Load{2,3,4}Aligned and LoadxAligned<T> functions of
buffer type. We assume that those aligned version of Load{2,3,4} and
Load<T> will treat the whole buffer as type of unit{2,3,4} or T,
so the address must be aligned to size of the loaded type.

This commit renames the files and projects to prefer "core-module" over
"stdlib".
The directory name `source/slang-stdlib` needs to be renamed too, and
there will be another commit for it soon.
|

This is a breaking change in a way that the Slang API function names are changed. All of them are commented as "experimental" and we wouldn't provide a back-ward compatibility for them.
Following functions are renamed:
compileStdLib() -> compileCoreModule()
loadStdLib() -> loadCoreModule()
saveStdLib() -> saveCoreModule()
slang_createGlobalSessionWithoutStdLib() -> slang_createGlobalSessionWithoutCoreModule()
slang_getEmbeddedStdLib() -> slang_getEmbeddedCoreModule()
hasDeferredStdLib() -> hasDeferredCoreModule()
Following command-line arguments are renamed:
"-load-stdlib" -> "-load-core-module"
"-save-stdlib" -> "-save-core-module"
"-save-stdlib-bin-source" -> "-save-core-module-bin-source"
"-compile-stdlib" -> "-compile-core-module"

* wasm: Add compile target option when creating slang session
Also add a new interface to return spirv code which is binary,
because 'std::string ComponentType::getEntryPointCode' is not
suitable for returning the binary data.
We use a more standard way that wrap the binary data by using
emscripten::val as the return type.

* Recognize a JSON keyword "aliases" for SPIRV-header
This commit will handle the new JSON keyword "aliases" in SPIRV-Header grammar files.
"aliases" are used in two places: one for "opname" and another for "enumerants".
This commit itself wouldn't do anything until we integrate new commits from SPIRV-Header repo.
