* ensure that fix<>float methods (not inline versions) are called too in VFP tests
* remove sf_table.h include from float.h as it is not part of the public API
* fix float->fixed/int infinite conversions via VFP
* 2 instructions -> 1
* add missing call_ tests for float2fix_z and float2ufix_z
* fix test descriptions

* fix issues with and improve tests for dcp conversions of INFINITES to fixed point values
* improve comments
* fix outstanding todo in __aeabi_dmul via DCP which improves speed/size
* fix missing DCP state saves for float2int, float2uint and float2fix
* slightly improve implementation of saturation of INFINITES
* should not include sf_table.h in double.h
* point out that float/double->fixed/int saturate in the docs
* move some doxygen into RP2350 specific and change include guards ro be RP2350 specific
* more doc tweaks
* fixup check names to be more consistent
* Enable hard-float ABI support for pico_float and pico_double on m33
Resolves#2783

* Add (non google) LLVM support, and replace calling convention check with #if defined(__ARM_PCS_VFP)
* switch float.h to use static inline method for int2float() etc in VFP mode rather than #define
* float/double test cleanup - particularly:
- splitting out executable for each test type for pico_float/double_test
- removing undefined behavior from custom_float_funcs_test.c, to de-confuse clang
- add test of denormal->int
Note some tests still fail on llvm libc (at least version 19)
* fix some issues with newer llvm_libc/compiler as used by bazel build
* keep check_configs happy
* another bazel issue
* introduce pico_double_pico_dcp for consistency
* fixup debug output based on previous commit
* remove unnecessary build guard from double_conv_m33.S
* allow -1 for neg_denormal->int rounding towards minus infinity
* Update test/pico_float_test/CMakeLists.txt

* - add fma/_fast functions to pico_float_test/pico_double_test
- fix guard for TEST_SATURATION in pico_double_test - GCC doesn't clamp either
* - double functions were only wrapped in pico_double_pico not pico_double_pico_dcp explicitly (i.e. explicitly setting double impl to pico_dcp was not selecting our versions)
* avoid extra stack alignment push (per review comment)
* fix fma return code in VFP mode (register transfer was the wrong way around)
* separate PCS=VFP and non-PCS-VFP versions of fma_fast
* remove saving_func_return (which is just bx lr) and fold the separate pop of lr, into a pop of pc
* better fix for wrapping right libraries
* rename some labels from _entry (which is an internal entry point) to _softfp to be clear that these are the function entry points which work with softfp calling conventions
* Make bazel pico_float build not wrap SCI functions on RISC-V to match CMake build
* Split out FMAF as a selectable wrapped item since we don't want to wrap it for VFP
* fix typos
* fix test

* on RP2350 _dcp variant now enables -msoft-float, since if you're using this at all it is likely because you don't want to use the VFP unit at all (to save stack space)
* implement all float_ and double_ conversion functions in all pico_float_pico_ variants and pico_double_pico on RP2040 and RP2350 (many were missing in some combinations)
* provide better granularity of what functions are wrapped in each case
also marked custom_xxx_funcs_test.c as not in bazel build yet
