I'm creating some CLs to set encoded/decoded sizes more consistently.

This should include getters (encodedSize/decodedSize).

ImageResource: Reset the encoded image size after receiving all data

Before this CL, an ImageResource's encoded image size remains non-zero
even after the encoded data is cleared. This CL fixes this to make
Resource::onMemoryDump report more accurate size.

Report the size of |ScriptResource::m_script| as decoded size

Previously, |m_script| was reported as encoded data, while it is not |m_data|.
This CL reports |m_script| as decoded data and call
setEncodedSizeMemoryUsage(0) instead, to prevent |m_script| from being
reported both as encoded and decoded data to memory-infra.

Report the size of |CSSStyleSheetResource::m_decodedSheetText| as decoded size

Previously, |m_decodedSheetText| was reported as encoded data, while it is
not |m_data|.
This CL reports |m_decodedSheetText| as decoded data and call
setEncodedSizeMemoryUsage(0) instead, to prevent |m_decodedSheetText| from being
reported both as encoded and decoded data to memory-infra.

This CL also makes setParsedStyleSheetCache() to always update the decoded
size, while the decoded size was not updated in some call sites of
setParsedStyleSheetCache().

Ensure setEncodedSizeMemoryUsage() is called when |m_data| is cleared

This CL
- Moves setEncodedSizeMemoryUsage(0) calls from the call sites of clearData()
  into the body of clearData(), which doesn't affect the behavior, and
- Replaces |m_data.clear()| in Resource.cpp with clearData(), so that
  the encodedSizeMemoryUsage is updated.

Marking as fixed. Feel free to refer to this bug if you find more inconsistencies around encodedSize()/decodedSize().
