We can leverage the FPU dirty state as an indicator for preemptively
reloading the FPU content when a thread that did use the FPU before
being scheduled out is scheduled back in. This avoids the FPU access
trap overhead when switching between multiple threads with heavy FPU
usage.

With lazy FPU context switching, k_float_disable() is merely triggering
a synchronous FPU context save and k_float_enable() is a no-op.

FPU context switching is always performed on demand through the FPU
access exception handler. Actual task switching only grants or denies
FPU access depending on the current FPU owner.
Because RISC-V doesn't have a dedicated FPU access exception, we must
catch the Illegal Instruction exception and look for actual FP opcodes.
There is no longer a need to allocate FPU storage on the stack for every
exception making esf smaller and stack overflows less likely.

Instead of saving/restoring FPU content on every exception and task
switch, this replaces FPU sharing support with a "lazy" (on-demand)
context switching algorithm similar to the one used on ARM64.
Every thread starts with FPU access disabled. On the first access the
FPU trap is invoked to:
- flush the FPU content to the previous thread's memory storage;
- restore the current thread's FPU content from memory.
When a thread loads its data in the FPU, it becomes the FPU owner.
FPU content is preserved across task switching, however FPU access is
either allowed if the new thread is the FPU owner, or denied otherwise.
A thread may claim FPU ownership only through the FPU trap. This way,
threads that don't use the FPU won't force an FPU context switch.
If only one running thread uses the FPU, there will be no FPU context
switching to do at all.
It is possible to do FP accesses in ISRs and syscalls. This is not the
norm though, so the same principle is applied here, although exception
contexts may not own the FPU. When they access the FPU, the FPU content
is flushed and the exception context is granted FPU access for the
duration of the exception. Nested IRQs are disallowed in that case to
dispense with the need to save and restore exception's FPU context data.
This is the core implementation only to ease reviewing. It is not yet
hooked into the build.

This reverts commit 5824ac90ecd8dd06d9ea117d345dbc6b069e5840.
The resulting revert takes into account changes to the predicate that
guards the use of `resp_addr`.
In the resulting revert, the predicate guarding the use of `resp_addr`
is differs from the naive revert because the intention of that predicate
is to know when `conn.c:bt_conn_le_create` decided to use the Host
resolver. And, the logic in `conn.c:bt_conn_le_create` has changed. The
changes to the logic in `conn.c` are in the following commits:

New LLCP will process the CIS establishement in the TX path, meaning it
will only process once every ACL connection interval.
If ACL connection interval is significantly longer than the ISO
interval, CIS packets corresponding to the ACL connection interval will
be lost. This may cause latency in audio rendition.
By processing the CIS establishment in the RX path, notification will be
sent immediately, and audio path is enabled fast to reduce latency.
When a CIS fails to establish, the controller shall complete the
procedure by sending a CIS_ESTABLISHED event containing the error.
