Created to prepare for a fix for https://github.com/material-components/material-components-ios/issues/7752.
`UIEdgeInsetsEqualToEdgeInsets` directly compares `CGFloat` number within two . The `MDCEdgeInsetsEqualToEdgeInsets` added in this PR compares UIEdgeInsets using `MDCCGFloatEqual` to take epsilon into consideration.
Replacing all non-integral, single-precision floating point literals with double-precision values explicitly cast to CGFloat. For example, `0.1f` should become `(CGFloat)0.1`.
Regex used:
```
([0-9]*\.)([0-9]*?)([1-9]+)([0-9]*?)[fF]
```

Removes the need to copy-paste stanzas from other files anymore as we'll rely on #4478 to generate the correct stanza for us instead.

An internal build failed (once) when compiling the Math tests because
double-precision floating point
values were being implicitly cast to single-precision. Marking each of these
as either single-precision float or CGFloat (where convenient). Except for the
tests that measure rounding errors, single- and double-precision isn't
important for the test outputs.
Sample error:
material_components_ios/components/private/Math/tests/unit/MDCMathTests.m:33:38: error: implicit conversion loses floating-point precision: 'double' to 'CGFloat' (aka 'float') [-Werror,-Wconversion]
CGRect misalignedRect = CGRectMake(0.45, 0.78, 1.01, 5.98);
~~~~~~~~~~ ^~~~
Rather than potentially returning a CGRectNull and causing UIKit crashes
if it's assigned to a view's frame or bounds, treat a scale of 0 as a
scale of 1.
Closes#2044
Although it is possible to currently align a CGRect (frame) to a
pixel-aligned bounding rectangle, in some cases manipulating the frame
is neither possible nor desirable (such as when the transform is not the
identity). Adding two new methods to support rounding a CGPoint to a
pixel and aligning the center point of a UIVIew given its bounds.
Adding a new function to realign a CGRect (frame) to pixel boundaries
based on the screen scale. After a review of the catalog, I'm updating
the areas where I found misaligned frames.
Closes#1723
