b63d4841a1 [fastcall] Turn the options pointer to a reference
Refactor the {options} output parameter of the fast callback to a
reference, since it can never be nullptr for functions created with
MakeWithFallbackSupport. This allows embedders to spare the nullptr
check.

4d5e6fb301 [fastcall] Generalize fallback option for fast API calls
Switch the current bool* parameter to a structure that contains
the boolean fallback flag and is forward compatible, if we decide
to add more options to the fallback call.

Fly-by refactoring: moved V8_ENABLE_FP_PARAMS_IN_C_LINKAGE out of
a public V8 header file.

fe947abf4d [turbofan] Add float/double support for fast API calls
This CL implements passing float parameters to fast API calls by
using the existing representation conversions for double parameters
and then truncating the double to a float.

It also adds float/double tests for fast API calls.

ca1e6573e4 [turbofan] Fast API calls support for default fallback
This change adds a has_error parameter on the stack
which allows the fast callback to report an error. In case
this parameter is set to non-zero, the generated code calls
the slow (default) callback, which can throw the exception.

b097a8e5de [api] Create v8::String::NewFromLiteral that returns Local<String>
String::NewFromLiteral is a templated function that takes a char[N]
argument that can be used as an alternative to String::NewFromUtf8 and
returns a Local<String> rather than a MaybeLocal<String> reducing the
number of ToLocalChecked() or other checks.

Since the string length is known at compile time, it can statically
assert that the length is less than String::kMaxLength, which means that
it can never fail at runtime.

This also converts all found uses of NewFromUtf8 taking a string literal
or a variable initialized from a string literal to use the new API. In
some cases the types of stored string literals are changed from const
char* to const char[] to ensure the size is retained.

This API does introduce a small difference compared to NewFromUtf8. For
a case like "abc\0def", NewFromUtf8 (using length -1 to infer length)
would treat this as a 3 character string, whereas the new API will treat
it as a 7 character string.

As a drive-by fix, this also fixes all redundant uses of
v8::NewStringType::kNormal when passed to any of the String::New*
functions.
