Various fixes to how timer differences are calculated (#8585) 
* tmk_core/common: Fixing TIMER_DIFF macro to calculate difference correctly after the timer wraps.

Let's go through an example, using the following macro:

If the first timer read is 0xe4 and the second one is 0x32, the timer wrapped.
If the timer would have had more bits, it's new value would have been 0x132,
and the correct difference in time is 0x132 - 0xe4 = 0x4e

old code TIMER_DIFF_8(0x32, 0xe4) = 0xff - 0xe4 + 0x32 = 0x4d, which is wrong.
new code TIMER_DIFF_8(0x32, 0xe4) = 0xff + 1 - 0xe4 + 0x32 = 0x4e, which is correct.

This also gives a chance for a smart compiler to optimize the code using normal
integer overflow.

For example on AVR, the following C code:
uint8_t __attribute__ ((noinline)) test(uint8_t current_timer, uint8_t start_timer)
{
    return TIMER_DIFF_8(current_timer, start_timer);
}
With the original code, it gets translated to the following list of instructions:
00004c6e <test>:
    4c6e:       98 2f           mov     r25, r24
    4c70:       86 1b           sub     r24, r22
    4c72:       96 17           cp      r25, r22
    4c74:       08 f4           brcc    .+2             ; 0x4c78 <test+0xa>
    4c76:       81 50           subi    r24, 0x01       ; 1
    4c78:       08 95           ret
But with this commit, it gets translated to a single instruction:
00004c40 <test>:
    4c40:       86 1b           sub     r24, r22
    4c42:       08 95           ret

This unfortunately doesn't always work so nicely, for example the following C code:
int __attribute__ ((noinline)) test(uint8_t current_timer, uint8_t start_timer)
{
    return TIMER_DIFF_8(current_timer, start_timer);
}
(Note: return type changed to int)

There is not much performance improvement in this case, however at least with this
commit it functions correctly.

Note: The following commit will improve compiler output for the latter example.

* tmk_core/common: Improve code generation for TIMER_DIFF* macros

Because of integer promotion the compiler is having a hard time generating
efficient code to calculate TIMER_DIFF* macros in some situations.
In the below example, the return value is "int", and this is causing the
trouble.

Example C code:

int __attribute__ ((noinline)) test(uint8_t current_timer, uint8_t start_timer)
{
    return TIMER_DIFF_8(current_timer, start_timer);
}

BEFORE: (with -Os)

    4c44:       46 2f           mov     r20, r22
    4c46:       50 e0           ldi     r21, 0x00       ; 0

    4c5a:       93 95           inc     r25
    4c5c:       08 95           ret

AFTER: (with -Os)

00004c40 <test>:
    4c40:       86 1b           sub     r24, r22
    4c42:       90 e0           ldi     r25, 0x00       ; 0
    4c44:       08 95           ret

Note: the example is showing -Os but improvements can be seen at all optimization levels,
including -O0. We never use -O0, but I tested it to make sure that no extra code is
generated in that case.OA

* quantum/debounce: Fix custom wrapping timers in eager_pr and eager_pk debounce algorithms

Please see the below simulated sequence of events:
Column A is the 16-bit value returned by read_timer();
Column B is the value returned by custom_wrap_timer_read();
Column C is the original code: (timer_read() % MAX_DEBOUNCE)

    A,     B,     C
65530,    19,    30
65531,    20,    31
65532,    21,    32
65533,    22,    33
65534,    23,    34
65535,    24,    35

    4,    29,     4
    5,    30,     5

read_timer() wraps about every 1.09 seconds, and so debouncing might
fail at these times without this commit.

Fix compile issues related to NO_ACTION_MACRO/FUNCTION and LTO_ENABLE (#8663) 
* Define NO_ACTION_MACRO/FUNCTION in header instead of makefile when LTO is enabled

Currently, boards and keymaps that define NO_ACTION_MACRO/FUNCTION unconditionally
will not compile with LTO_ENABLE (#8604). This fixes the issue by moving the
definitions from common.mk to action.h, which enables us to check for previous
definitions of those macros (this cannot be done in a makefile).

* Remove LTO checks in templates

Since now NO_ACTION_MACRO/FUNCTION are defined as needed in action.h (which is
included by quantum.h), checking for LTO in keyboard and user code is no
longer required.

* Update LTO_ENABLE docs
